Abstract:

Problems of SPIN's（Sensor Protocol for Information via Negotiation） too complicated data forwarding and repeated
forwarding of the same packet affect its performance on network throughput and increase the packet loss rate and reduce the network
lifetime. To solve these problems, a SPIN protocol based on dynamic routing called D-SPIN protocol is proposed, which is based on
SPIN but adds the strategies of dynamic routing table creation and algorithm and next hop id verification and selective forwarding. DSPIN
can effectively improve network throughput, decrease the packet loss rate and extend the network delay. NS2 software is used to
simulate and the results show that D-SPIN protocol has a more significant improvement in throughput, packet loss rate and the network
delay than SPIN protocol.
