Wireless Sensor Network (WSN) consists of large number of sensor nodes which are limited in battery power and communication range and are having multi-model sensing capability. One of the most significant applications of wireless sensor network is environment monitoring. A Wireless Sensor Network (WSN) entail of spatially distributed self-sufficient sensors to monitor physical or conservational requirements, such as pressure, sound, vibration, temperature, motion or pollutants and to collaboratively pass their data to a main location(base station or sink) through the network. Wireless sensor networks are equipped with only Omni-directional antennas, which can cause high collisions.
