The field of communications networks continues to emerge, thus leading to the rapid growth in the field of Wireless Sensor Networks (WSNs). WSNs are noticeably different from traditional Ad hoc networks. The conspicuous difference between WSNs and traditional Ad hoc networks is that they (WSNs) are strictly constrained by limited supply of energy, capacity of storage, power of computation, and bandwidth. Because of these constraints and random deployment in some cases, it has become a challenge for the researchers to design an unblemished routing layer protocol for wireless sensor networks.
