Dynamic Source Routing

No. 254-260. Month, Year: December 2014 1. INTRODUCTION: The approach of route cache in DSR protocol is used to stock a route that is learned from the source node and to avoid needless route discovery operation in each time the data packet is to be transmitted. It is needs to start again the route discovery mechanism in reactive on demand routing protocols, as it is very costly in

DSR is a reactive protocol and therefore doesn’t use periodic updates of routing information. It computes the routes whenever needed and then maintains them. The distinguishing feature of Dynamic Source Routing (DSR) is the use of source routing technique in which the sender of a packet determines the complete sequence of nodes through which the packet has to pass. The sender lists this route in the packet’s header, to identify each forwarding “hop” by the address of the next node to which to transmit

Balancing In Wdm Networks For Dynamic Route Maha Elnour Mekki Awoda1, to Prof. Dr. Aisha Hassan A. Hashim2, 1Faculty of engineering, Dept: M.S.C Data Network and Communications Batch No.3, AL – Neelain University 2Faculty of Engineering, International Islamic University Malaysia (IIUM Abstract: This study deals with the formulation of an effective and efficient algorithm for load balancing in WDM networks. Here we develop a Load Balancing algorithm for IP-like Routing. The considered networks are

timers 1) Update Timer – indicates how regularly the router will send out a routing table update. 2) Invalid Timer – indicates how long a route will remain in a routing table before being marked as invalid, if no new updates are heard about this route. The invalid timer will be reset if an update is received for that fussy route before the timer expires. A route marked as invalid is not immediately removed from the routing table. Instead, the route is marked with a metric of 16, indicating it is unreachable

This paper introduces a new routing mechanism for MANET communication by using proactive & reactive defense scheme known as Hybrid Defending against Collaborative Black hole Attacks & Gray Hole Attacks. Proposed Scheme is known as CBDS (Co-Operative Bait Detection Scheme) which is based on DSR Based Routing Protocol for Mitigating against Variants of Collaborative Attacks. CBDS is already proposed for MANET but in this paper MANET provides smooth, efficient & secure routing in MANET by using Reverse

users will be the need for the next generation wireless communication systems. A mobile ad-hoc network is a collection of mobile users that communicate over constrained wireless links with lower bandwidth. Network scenarios which include establishing dynamic communication for emergency/rescue operations, survivable, efficient, disaster relief efforts and military networks cannot rely on organized and centralized connectivity. Networks are known as ad hoc because

to direct the packet from source to destination in the network. All nodes acts as routers and are capable of discovering and maintaining routes to propagate packets to the destinations.[2] There are lots of advantages promised of network in terms of cost and flexibility compared to network with infrastructures. Ad-hoc network are used for a great variety of applications such as data

[2]. In on-demand or reactive routing protocols, the routes are created on requirement basis. To find a path from source to destination, it invokes the route discovery mechanisms. Only the routes that are currently in use are maintained, thereby maintaining low control overhead and reducing the network load since a small subset of all available routes is in use at any time [1]. Existing routing protocols in ad-hoc networks utilize the single route that is built for source and destination node pair.
