It is necessary to consider the energy efficiency of nodes and load balance in wireless sensor networks. This paper combines with the network of the actual heterogeneous nodes, the improved algorithm of LEACH is proposed, which is called LEACH-HA. The optimal number of cluster heads is derived with improved in the network which increases energy of nodes become cluster probability. A hybrid communication mode that cluster heads alternate between single hop and multi-hop mode is proposed. After analysis LEACH-HA improves the energy efficiency among nodes and expands the coverage of network.

the clustering routing protocol has excellent network scalability and efficient communication efficiency. This paper has a study on the representation of protocol ----LEACH protocol. We have proposed multi-hop clustering routing protocol for the theory of wireless sensor networks. We can use multi-hop relay to save energy as the energy consumption of the edge node in the cluster considered. Because the multi-hop algorithm will increase the energy consumption of the relay node, we make theory formula derivation and simulation for multi-hop cluster in the ideal case and prove the obvious low-power performance. The lifetime of the global network has been significantly improved. It is important to highly use of energy for wireless sensor network. Keywords-LEACH protocol, multi-hop, the relay node, energy saving2013 Third International Conference on Instrumentation, Measurement, Computer, Communication and Control 978-0-7695-5122-7/13 $26.00 H 5 According to the above formula and formula 1, long distance communication is easy to cause nodes of the cluster edge to die because of energy depletion to affect the network survival time. This paper researches on the cluster multi-hop communication mode which could replace single-hop communication between the distant member nodes and cluster head. It would reduce the communication energy of the cluster edge nodes to balance the network energy consumption, and prolong the network life cycle.

Considering the shortcoming of the traditional Greedy Perimeter Stateless Routing Protocol in the Vehicular Ad hoc Networks ,this paper focuses on an improved GPSR protocol based on the density of vehicle flow .This new scheme includes macro-directing algorithm , micro-forwarding strategy and the maintenance of the neighbor list.The simulation result shows that compared with the traditional GPSR protocol, the new GPSR protocol improves data packet delivery ratio, but its average end-to-end delay is slightly larger than before.
