A Wireless Sensor Network (WSN) consists of cheap and simple processing devices, called sensor nodes. The sensor nodes have the capability of sensing parameters, such as temperature, humidity and heat. The sensor nodes communicate with each other using wireless radio devices and form a wireless sensor network. The WSN has a dynamic, continuously changing network topology which makes routing difficult. Another characteristic of the WSN is its band width and power constraints. Silva et al., have implemented a traditional Multicast Ad hoc On demand Distance Vector (MAODV) on the WSN and claim that multicast routing improves the performance of the WSN.
