【摘要】：針對現(xiàn)有ZigBee網(wǎng)絡(luò)多PAN路由算法在路由構(gòu)建過程中通信開銷、傳輸時延和能耗較大的問題,提出一種基于跨層機(jī)制的能耗均衡路由算法——ERBCD(Energy-balanced Routing algorithm Based on Cross-layer Design)。該算法采用梯度探測反饋方式構(gòu)建網(wǎng)關(guān)至節(jié)點的下行多徑路由;引入跨層機(jī)制更新鄰居節(jié)點的剩余能量信息;設(shè)計包含跳數(shù)和節(jié)點剩余能量的合成路由度量標(biāo)準(zhǔn)以減輕節(jié)點負(fù)載,均衡網(wǎng)絡(luò)節(jié)點能耗。理論分析證明了ERBCD算法的有效性。仿真結(jié)果表明與現(xiàn)有典型算法IP-AODV相比,ERBCD算法大大降低了網(wǎng)絡(luò)通信開銷和數(shù)據(jù)分組平均能耗,并延長了網(wǎng)絡(luò)生存期延。
[Abstract]:In order to solve the problem of communication overhead, transmission delay and energy consumption of existing multi-#en1# routing algorithms in ZigBee networks, the problem of communication overhead, transmission delay and energy consumption in routing construction is analyzed. An energy balance routing algorithm based on cross-layer mechanism, ERBCD-balanced Routing algorithm Based on Cross-layer design, is proposed. The algorithm uses gradient detection feedback to construct downlink multipath routing from gateway to node, and introduces cross-layer mechanism to update the residual energy information of neighbor nodes. A composite routing metric that includes hops and node residual energy is designed to lighten the node load. The theoretical analysis proves the effectiveness of the ERBCD algorithm, and the simulation results show that the proposed algorithm greatly reduces the network communication overhead and data packet average energy consumption, and prolongs the network lifetime compared with the existing IP-AODV algorithm.
