Abstract

The paper presents a novel proactive algorithm for routing called Intelligent Ant Routing (IAR), in mobile ad hoc networks, which is inspired by Ant Colony Optimization (ACO) framework and uses "ants" for route discovery, maintenance and improvement. The design for the protocol lies in a heuristic, based on bio inspired routing, which takes into account the limited resources in highly dynamic environment. The algorithm is based on a modification of the state transition rule of ACO routing algorithm which results in maintaining higher degree of investigation leads to reduced end-to-end delay and also lowers the overhead at high node density. The comparative result of proposed algorithm IAR with AODV reactive routing algorithm exhibits superior performance with respect to reactive AODV routing algorithm in terms of end-to end delay. It is also tested for different network sizes and node mobility.

Abstract

Wireless ad-hoc networks have recently emerged as a premier research topic. A mobile ad-hoc network is a collection of wireless mobile hosts dynamically establishing a short lived network without the aid of any centralized administration or standard support services of a network infrastructure. In such an environment, it may be necessary for one mobile host to enlist the aid of others in forwarding a packet to its destination, due to the limited propagation range of each mobile host‟s wireless transmissions. For mobile ad hoc networks one of the fundamental problem is routing .Many routing protocols (e.g., DSDV, TORA, etc) have been proposed for MANETs. However, most assume that nodes are trustworthy and cooperative. We propose a Dynamic routing protocol based on DSDV, namely D-DSDV, in which, a well-behaved node can successfully acting as a specialized router which periodically advertises its view of interconnection topology with other mobile hosts within the network. We compare security properties and efficiency of D-DSDV with DSDV. Our efficiency analysis shows that D-DSDV generates high network overhead, however, which can be reduced by configurable parameters.
