A Wireless Sensor Network (WSN) is a collection of thousands of tiny sensor nodes having the capability of wireless communication, limited computation and sensing. Many data dissemination protocols have been proposed for multi-hop communication in sensor networks, each evaluated in some scenario. Many protocols are designed to exploit application requirements, then no one protocol can be optimized for all applications. Directed diffusion is a prominent example of data-centric routing in sensor networks, since it is based on application layer data and purely local interactions. However; its functioning relies heavily on expensive operations, like network-wide flooding. The purpose of this paper is to explore different directed diffusion protocols and their performance as the number of sinks and sources increases, the traffic rate and node placement varies, and with and without geographic proximity in node placement. We present the simulation-based performance evaluation using NS2 and tuning of data dissemination in wireless sensor networks. Hope our result would be useful to match dissemination algorithms to application performance requirements.
