A Fuzzy based Routing Protocol for Delay Tolerant Network

Abstract

Delay Tolerant Network (DTN) is a wireless ad hoc network that intends to provide communication between pair of nodes in spite of having intermittent connectivity and long delays.The nodes are buffer and energy constrained.To provide communication in such scenario, a sturdy routing mechanism is needed.In this paper we propose a new routing technique based on fuzzy logic for intermittently connected network.Also an effort has been made to evaluate the performance of the proposed routing strategy in realistic environment (having obstacles) in MATLAB.The simulation results show that the performance of the network is improved using fuzzy logic based routing strategy and the results of realistic environment are quite different from idealistic environment.
