A Comparison of Data Dissemination Protocols for Wireless Sensor Networks
Due to many constraints of nodes in wireless sensor networks, a variety of data dissemination protocols have been developed for data gathering in wireless sensor networks. Sensors extract useful information from environment; this information has to be routed through several intermediate nodes to reach the destination. Effective information dissemination is one of the most important tasks in sensor networks. Directed Diffusion is a communication paradigm for information dissemination in WSNs based on data centric routing. In this paper, the authors simulate three protocols using ns-2.33 simulator in terms of remaining energy and routing load.
