To tackle the limitation of LEACH,PEGASIS and PEDAP,a multi-layer energy-efficient and delay-reducing chain-based data gathering protocol(MEDC)for wireless sensor network was presented in consideration of the characteristics of wireless sensing traffic monitoring network(WSTMN) such as band monitoring area,high-speed target,long-distance base station and restricted network density.The protocol put forward the idea of multi-layer chain,and used the minimum total energy algorithm to construct the chain.Moreover,the maximum residual energy of nodes was the standard for selection of leaders.The experimental results show that MEDC works better than LEACH and PEGASIS.It can not only prolong the network lifetime,but also reduce the network delay.
