Opportunistic routing employs transmission coordination mechanism (TCM) to reduce the total number of packet transmissions so as to improve end-to-end throughput. Existing paradigms use batch map to record the progress of packets transmitted in batch mode towards to destination, and then achieve distributed transmission coordination by exchanging batch map among candidate forwarders. However, the...
This paper presents an improved clustering routing protocol, ILEACH which based on the characteristic of limited energy of wireless sensor networks to prolong the lifetime of the whole networks. It takes nodes' residual energy into consideration during the process of cluster heads being elected. The constraint threshold of distance is used to optimize cluster scheme. Furthermore, it also constructs...
