Wireless sensor network is important in sensing, Collecting and disseminating information about environmental Phenomenon.This paper contain emerging field to classify wireless micro sensor network according to different communication functions, data delivery models and network dynamics.This taxonomy will aid in defining appropriate communication infra structure for diff.sensor network application subspaces.It allows network designer to choose the Protocol architecture.According to their application this taxonomy will enable new sensor network models to define for use in further research in this area.The overall communication behavior in a wireless micro sensor Network is application driven.It is useful to decouple the application communication used for information dissemination from the infrastructure communication used to configure and optimize the Network.This separation will aid network designers in selecting the appropriate sensor network architecture that will best match the characteristics of the communication traffic of a given application.This will allow the network protocol to achieve the application-specific goals of energy-efficiency, low latency, and high accuracy in the sensing application.We also believe that a sensor-initiated proactive path recovery approach with local patching will be beneficial in efficient information dissemination in wireless micro-sensor networks.The taxonomy presented will be helpful in designing and evaluating future network protocols for wireless micro-sensor networks.Often, it is possible to implement a sensor network for a specific phenomenon in a number of different ways.Consider the problem of monitoring a tornado.One option would be to fly airplanes to sense the tornado (mobile phenomenon; mobile sensors; continuous data delivery).Another would be to have a sensor grid statically placed on the ground and report data as the tornado passes through (mobile phenomenon; static sensors; continuous data delivery).Yet another would be to release lightweight sensors into the tornado (static phenomenon; mobile sensors; Continuous data delivery).
