Energy efficient copy distributing status aware routing mechanism in opportunistic network
Ruyan Wang · Journal of Communications · 2013
In opportunistic network,the relation between the node energy and message spreading degree is tradeoff.As a result,the network performance can be dramatically improved in limited resource scenarios by an effective routing mechanism considering the node energy and copy status.Both the message spreading degree and node residual energy were taken into consideration,and then combined with the encounter probability predicting methods,an energy efficient copy distributing status aware routing mechanism was proposed,which could be used to choose the relay nodes reasonably.Numerical results show that the overhead can be reduced efficiently,and the message delivery ratio and latency can also be optimized.
