A new algorithm for high power node multicasting in wireless sensor networks

Multicast routing protocols normally depend upon the standard establishment of a multicast tree that needs maintenance of state information by individual nodes. In the case of dynamic networks with burst traffic, between the bursts of data, a long period of silence is expected. The multicast state preservation appends a huge amount of transmission and memory overload. This is no longer suitable for any applications. Therefore, this paper proposes a stateless high power node multicasting method utilizing a group of sink node data, which are implanted in packet headers, to facilitate recipients to fix the finest technique to send data packets in the multicast traffic. In order to eliminate expensive state information of the neighbor table, the HPN multicast protocol utilizes the awareness of the exact positions of sensor nodes. This protocol will be preferably appropriate for multicasting in active networks. The simulation results confirm that HPN multicast affords elevated success rates and little delay exclusive of the trouble of state information.
