The complexity and memory requirements of the algorithm are in the order of $D_\mathcal{D}.{\rm N}$, denoted as $O(D_\mathcal{D}{\rm N})$. The algorithm become more effective when the minimum difference $\Delta Y_k$ is large between the transmission probability gains $Y_k$. Consequently, our algorithm finds an optimal solution coupled with linear complexity, when the network become more heterogeneous due to small ${\rm N}$. Our algorithm also finds the optimal solution with an increased complexity, when the network becomes more homogeneous or less heterogeneous due to increasing ${\rm N}$. The quantization precision ${\rm N}$ in Algorithm 1, is a physical quantity specified by the underlying network that elaborate the designing of quantization step. The total content size $H$ depends on the required content transmission rate $r_{c_i, d_i}$ and $Y_k$, whereas $Y_k \sigma$ are defined by the contact dynamics of the nodes in a network. However, if the network is difficult by the required level of transmission ratio, the values of $Y_k$ and the value of $\Delta Y_k$, such that $\rm N$ is too large, then the designer may have to comprise by reducing the desired level of transmission ratio to reduce $\rm N$. In results, the sub-optimal

We were assigned to construct a software that utilizes a classification algorithm that is able to accurately decide a correct classification for a certain sequence of inputs that were provided by the user. The input is to be classified based on a known training set of records of the same attributes as the sequence provided by the user.

In order to mix the good strings and protect the effective ones simultaneously, the probability of crossover and mutation are considered as 0.8 and 0.1 respectively. This entire process is repeated, until the improvement in fitness values (from previous to current Pareto-optimal set) is less than a chosen precision, ǫ. Undoubtedly, actual precision value (ǫ) will be distinct according to corresponding QoS parameters. 10−6, 10−5 and 10−3 are chosen as the precision values for the probabilities of end-to-end delay, total bandwidth and overall energy consumption respectively. Finally, the strategy returns the results of the discovered QoS-route (whether success or failure and the set of routes) to the cross-layer QoS-provisioning algorithm shown in Figure

We have simulated another network having 30 numbers of nodes. The simulation is made using the same platform used for network 1. This simulation is done taking node 1 as a source and node 28 as destination. The optimal path obtained in this simulation is 1-23-13-28, in which data rate is 0.47 kbps. The second optimal path is 1-17-28, in which data rate is 0.35 kbps. The simulated results are summarized here in

Hadoop1 provides a distributed filesystem and a framework for the analysis and transformation of very large data sets using the MapReduce [DG04] paradigm. While the interface to HDFS is patterned after the Unix filesystem, faithfulness to standards was sacrificed in favor of improved performance for the applications at hand.

routing. In this chapter, we introduce some popular routing protocols in each of the three

There are number of metrics which are helpful for deciding the efficiency of a protocol. In this work the parameters used to evaluate the efficiency of a protocol are the packet delivery ratio, packet statistics in the network and the throughput of the network. The protocols AODV and AODVBC are checked against these parameters for their performance. Packet delivery ratio of the network is improved as the mobility with respect to the number of nodes changes. Increase in the PDR (Packet delivery ratio is because of the less number of packet drops when AODVBC is used. Fig. 4 justifies the better performance of AODVBC routing protocol over AODV protocol in terms of less number of packets drop.

Under high traffic conditions, this works very well, and backpressure is able to fully utilize the available network resources in a highly dynamic fashion. Under low traffic conditions, however, because many other nodes may also have a small or 0 queue size, there is inefficiency in terms of an increase in delay, as packets may loop or take a long time to make their way to the destination. This is particularly of concern in intermittent encounter-based mobile networks which are already delay-limited due to the sparse and highly dynamic network connectivity. Such networks have proposed the use of redundant transmissions to improve delay, which do not work well when the traffic load is high.

The purpose of the CDSWS scheme introduced in [52], is to extend the life of the network while ensuring network coverage. This proposal divides the sensor nodes into clusters based on the sensitivity of the coverage metrics and allows more than one node in each cluster to maintain activity simultaneously through the dynamic node selection mechanism. The dynamic rejection scheme was also presented to overcome the failure problem during cluster combining process, which has not been studied in depth before. The simulation results show that CDSWS outperforms some of the other algorithms in terms of coverage assurance, algorithm efficiency and energy saving. However, this concept assumes that some resource-rich nodes are available and need to be synchronized, which means maintenance costs. In addition to the burdens caused by re-clustering and re - registration making the distributed directories concept less suitable for dynamic IP-enabled LLNs.

After extensive studies on the analytical properties of the optimal solution, MDSCR heuristic algorithm is presented to achieve an effective service composition and recovery solution for ad hoc networks with anonymous node mobility. Simulations results conducted with using the proposed MDSCR algorithm in various network environments, reveals that the presented algorithm can achieve better performance than traditional methods.

A Mobile Agent starts from every node and moves to an adjacent node at every time. A node visited next is selected at the equivalent probability. The MA brings its own history of movement and updates the routing table of the node it is visiting [1].

Node can adapt to changing history of connections using the contact patterns. To reduce the space to store contacts a node can delete old history contacts. Direct contact probability is also taken into consideration. We need the kth order probability for the above contact sequence of k nodes. The k-order probability is thus defined using equation (4) by induction,
