Abstract: In a wireless sensor network where nodes have limited energy and forward messages of different priorities are frequent in the context of wireless sensor networks. So introduced several selective message forwarding policies to save energy and extend the lifetime of WSN. Forwarding schemes were designed for three different scenarios:1) when sensors maximize the importance of their own transmitted messages ; 2) when sensors maximize the importance of messages that have been successfully retransmitted by at least one of its neighbors; and 3) when sensors maximize the importance of the messages that successfully arrive to the sink . The three schemes have been compared under different criteria. From an overall network efficiency perspective, the first scheme performed worse that its counterparts, but it required less signaling overhead. More sophisticated schemes will achieve better importance performance, but will also require information from other sensors. It is a greater impact on the overall network performance.
