Wireless Sensor Network (WSN) is emerging as a major research field in computer networks over the last decade due to its wide variety of embedded real time applications. Sensor networks have infrastructure-less architecture because of frequently varying topology and link status. Routing is an extremely challenging task for battery-powered resource-constrained WSN, since it is main cause for energy depletion and energy must be utilized prudently to enhance lifetime for sensor networks. This drives a myriad of research efforts aiming at efficient data dissemination. In this paper, the authors analyze how efficiently MANET specific routing protocols OLSR (Optimized Link-State Routing protocol), DYMO (DYnamic MANET On-demand) and ZRP (Zone Routing Protocol) perform in IEEE 802.15.4 enabled wireless sensor networks and evaluate their simulation results using Qualnet simulator.
