Optimization of Dynamic Source Routing Protocol with Effective Resource Management
This paper proposes optimization of DSR (Dynamic Source Routing) protocol in aspect of cache size and cache expiry time to meet Quality of Service requirements between source and destination node pairs. The nodes are assumed to use a TDMA (Time Division Multiple Access) based MAC (Medium Access Control) layer. Given a set of Q o S requirements, a set of wireless nodes and their initial position...
متن کاملOptimization of OLSR Routing Protocol with Effective Resource Management
Mobile Ad hoc networks (MANET) allow a set of wireless hosts to exchange information without any special infrastructure. Limited battery power is one of the most important issues in mobile ad hoc network as the mobile nodes operate in limited battery power. Also there occurs a problem of broken links due to the lack of energy which cause disorder in network system. Such problem occurs due to th...
متن کاملPerformance Analysis of Dynamic Source Routing Protocol
Dynamic Source Routing (DSR) is an efficient on-demand routing protocol for mobile ad-hoc networks (MANET). It depends on two main procedures: Route Discovery and Route Maintenance. Route discovery is the procedure used at the source of the packets to discover a route to the destination. Route Maintenance is the procedure that discovers link failures and repairs them. Route caching is the sub p...
متن کاملSecurity-Aware Adaptive Dynamic Source Routing Protocol
We present SADSR (Security-Aware Adaptive DSR), a secure routing protocol for mobile ad hoc networks. SADSR authenticates the routing protocol messages using digital signatures based on asymmetric cryptography. The basic idea behind SADSR is to have multiple routes to each destination and store a local trust value for each node in the network. A trust value is assigned to each path based on tru...
متن کاملSecure Trust Management with Source Routing Protocol for MANETs
A MANET, in order to work properly, needs its nodes to work collaboratively. This is not always the case, and thus tools are developed to detect and identify uncooperative nodes. In this paper we present TADSR, a protocol based on an already existing secure routing protocol on top of which it adds trust management features. Our aim is to detect rogue nodes, and also to improve the overall perfo...
