| Mobile wireless sensor networks have the perception, mobile communications, processing and other functions, compared with the static network, the mobile nodes will lead to network topology change accordingly.The traditional static routing protocol for mobile wireless sensor networks often lead to data transmission delay,loss and energy waste.In addition,due to the current research of wireless network is no longer limited to two-dimensional plane, wireless sensor networks are applied more widely present in three-dimensional space.So this paper designs a3D energy-efficient routing protocols for sensor networks of mobile nodes.Firstly,this paper extends traditional clustering routing protocol to three-dimensional space to achieve a3D-LEACH protocol, and optimize their cluster head selection mechanism design of3D-LEACH-D protocol,compared with3D-LEACH protocol and3D-DEEC protocol under the same network conditions.The results show3D-LEACH-D protocol’s energy-saving effect is very good.Then,it put forward an energy saving routing protocol for mobile nodes in three-dimensional space3D-NMEERPL protocol.The paper describe the model of sensor nodes in detail,3D-NMEERPL protocol has several new points during the design process,such as in the establishment phase,it designs a new cluster selection mechanism based on the optimal cluster heads and energy adapt threshold,and in the stable phase, it designs a routing mechanism based on blocks and multi-hop and a energy-aware data transmission strategy.These new strategies allow the protocol to balance the energy consumption of each node.Finally,the3D-NMEERPL protocol is transplanted to the MATLAB simulation platform for testing.Based on simulation result,we find3D-NMEERPL protocol can reduce the overall energy consumption of network,prolong the lifetime of network and increase the amount of reception data effectively comparing with3D-LEACH protocoland3D-DEEC protocol.The proposed protocol has good energy saving effect. |
