Wireless sensor networks comprises of the upcoming technology that has attained noteworthy consideration from the research community. Sensor networks comprise of many small, low cost devices and are naturally self organizing ad hoc systems. The function of the sensor network is monitoring the physical environment, collect and transmit the information to other sink nodes. In general the range of the radio transmission for the sensor networks are in the orders of the magnitude which is smaller than the geographical extent of the intact network. Hence, the data has to be transmitted hop-by-hop towards the sink in a multi-hop manner.
