Improvement of Network Lifetime of WSN Using Controlled Mobility Algorithms
In wireless sensor networks (WSNs), many sensor nodes which have limited energy sense the environment and relay their packets to the sink node by multi-hop routing. Thus, the nodes closest to the sink consume more energy than the other nodes and this ends up their lifetime early, which affect the overall network lifetime. Among several techniques of improving the performance of a WSN, the controlled mobility technique is commonly used for some of the network nodes and considered as one of the most important.
