[pic] ZigBee Wireless Mesh Networking for Monitoring & Control What is ZigBee? ZigBee is a consortium of software, hardware and services companies that have developed a common standard for wireless networking of sensors and controllers. While other wireless standards are concerned with exchanging large amounts of data, ZigBee is for devices that have smaller throughput needs. The other driving factors are low cost, high reliability, high security, low battery usage, simplicity

the role of host and router are done by the same mobile node. It means that a node has ability to work both as host and router. Nodes perform switching functions as router and so endpoints and switches are same. 2.4. Dynamically varying topology: The topology of the Manets is dynamic as the nodes in the network are mobile. As time goes on, nodes move in random manner and so routes are established dynamically. 2.5. Poor link capacity: Compared to wired links, the reliability, scalability, efficiency

The Linear Bus Topology has all of the nodes connected to on single connection medium which has two end points. This type of set-up has multiple advantages, such as it is easy to set-up, it requires the least amount of cables, low cost, and it is used for small LAN’s. The distributed Bus Topology is a more complicated version of a Bus network. Unlike the Linear Bus, the Distributed Bus has more than two end points. This setup starts out looking like the linear bus with a main trunk cable that is

2.3.1 Introduction Leader election is a primary problem in distributed systems where it is important to coordinate processes group communications and activities. The leader is responsible for controlling and coordinating all communications between processes in the network, absence of the leader makes the overall system inconsistent, and loses the system reliability. To keep the system consistent, it is necessary to nominate another leader, the LEA solves this problem by deciding which process will

Network on Chip Architectures [1]S.Sariga, [2] C.Nandagopal [1]PG Scholar, M. Kumarasamy College of Engineering, [2]Assistant Professor, M. Kumarasamy College of Engineering ABSTRACT— As the feature size is continuously decreasing and integration density is increasing, interconnections have become a dominating factor in determining the overall quality of a chip. Due to the limited scalability of system bus, it cannot meet the requirement of current Systemon-Chip (SoC) implementations where only

Suneel Pasupuleti Student Id 1460391 Home work 1 Problem 3 a)As per given Application Working Module we have to use Circuit Switched Network for this Application.because as per given data application needs long time connection and a good bandwidth.if we used Packet switching we have to face some data loss and packet trafficking because there is no end to end connection between source and destination.so the best network is Circuit Switched Network for this given Application. b)if we are using

An Efficient Protocol for Service Discovery in Wireless Sensor Networks In [40],introduced simple service discovery protocol targeting to minimize the number of messages in the network while at the same time ,keeping the waiting time for services at minimal. Moreover,the performance of the stationary wireless sensor network is assessed. Remote procedure calls are used to retrieval a service once it is discovered, which permits for richer and parameterized interaction with the sensor

computer network design can be set up rather simple. The computers can be set up in a line, for the cash registers, with computers in the office being at one end. "Networks are usually classified using 3 properties: Topology, Protocol, and Architecture." (Network Structure, 2001) The bus topology, where the computers are attached to a common cable called a bus or backbone, is appropriate for a line of computerized cash registers and the office since they are all arranged in a single line. The protocol would

The most broadly utilized LAN innovation is the Ethernet and is indicated in the standard IEEE 802.3. Ethernet utilizes a star topology as a part of which the individual devices are connected with each other by means of dynamic network hardware, for example, switches. Star topology permits clients to effectively extend and include more workstations. With the Star Topology set up, the Ethernet system would be picked utilizing 100BaseTX standard, Cat5 UTP links with information rates of 100Mbps. The
