Executive Summary

Routing presents a significant design challenge to meet various applications requirements in Wireless Sensor Networks (WSNs) communications. In this paper, the authors present a minimum delay multipath routing protocol with modification to the standard Dynamic Source Routing (DSR) protocol, which aims to improve energy efficiency and minimize end-to-end delay to provide Quality of Service (QoS) support for delay sensitive applications in WSNs. The presented Energy-Efficient DSR (EEDSR) protocol takes into account, end-to-end delay and reliability of wireless channel links to establish a routing metric used to determine the cost associated with individual routes between a source node and a destination node. Each source node records multiple disjoint routes to the same destination.
