We address the problem of maximizing the lifetime in a wireless sensor network with energy- constrained sensor nodes and mobile data collection points (sinks). Information generated …
It is a known phenomenon that in a wireless sensor network, sensors communicating directly with a sink deplete their energy faster than the others. As a result, the so-called neighboring …

We address the problem of maximizing the lifetime of a wireless sensor network with energy- constrained sensors and a mobile sink. The sink travels among discrete locations to gather …
Wireless sensor networks basically consist of low cost sensor nodes which collect data from environment and relay them to a sink, where they will be subsequently processed. Since …

Network lifetime maximization is challenging particularly for large-scale wireless sensor networks. The sensor nodes near the sink node tend to suffer high energy consumption due …
Unbalanced energy depletion is a well-known problem in wireless sensor networks which is causing hot spot problem as a result of multi-hop communication to forward data to the static …
