Energy-efficient and low-latency MAC protocol for wireless sensor networks
Siwang Zhou · Journal of Computer Applications · 2006
In sensor networks,data forwarding from multi-source to sink forms a data gathering tree.For this gathering tree an energy-efficient and low-latency LD-MAC protocol was proposed to solve the conflict of energy-efficient and low-latency in previous MAC protocols.On one hand,LD-MAC adopted asynchronous duty cycle to reduce energy consummation.And on the other hand,by delaying the nodes' sending time and staggering their receiving and sending time hop by hop,it can reduce data forwarding latency.The analysis and simulations show that LD-MAC can solve the conflict efficiently.
