RRM-B: Reliable retransmission mechanism for wireless sensor networks
Wireless sensor network is a multi-hop self-organization formed by a lot of energy-limited sensor nodes. It is widely used in security surveillance, intelligent transportation, smart home, environmental monitoring and so on. The mechanism of data is the important part of the wireless sensor network. However, due to the limit sensor energy and poor channel quality, The reliability of the transmission cannot meet the requirements, so how to ensure the reliable data to the destination node is key point of the wireless sensor network. Data retransmission can improve the reliability of transmission for Wireless sensor network. For this, we introduce a reliability routing protocol based on information calculate algorithm model. The simulation results show that the proposed algorithm is energy saving, not only reducing the packet drop rate over networks, but also improving effectively the network transport fairness and the average network latency.
