| Popis: | 93 Since the sensor networks is large scale and energy constrained, how to reserve and use energy efficiency is an important issue. It is found that if there is lack of load balancing schemes, some nodes in the sensor networks will suffer heavy traffic load and die soon. Once nodes die, other nodes must consume more energy to maintain connectivity and coverage. At the end of the network lifetime, there will be some nodes that still have sufficient energy, but the network can’t work anymore. So, if we can evenly distribute the energy consumption to nodes in the sensor networks, the network lifetime is expected to be longer. In this thesis, we present an energy-efficiency and load balancing algorithm that can help to balance the load of cluster heads and reduce such unnecessary energy consumption. From the simulation result, the load of cluster heads will tend to the mean value, and the network lifetime can be improved. |
