Modification of Routing Protocols of the Wireless Sensor Network for Increasing the Network Life Expectancy

The main drawback of a wireless sensor network is the low power batteries which significantly limit the life expectancy of a network. There is irregular energy consumption in the nodes of the network; as a result the network becomes unable to perform at a certain moment when the electricity runs out in some network nodes, regardless of the biggest part of the network still working. There are several unconventional solutions where sometimes the wireless sensor network is used in an unordinary way, for instance, for transmission of multimedia data, the data processing of momentum sensors in tracing software’s for detecting moving objects as well as monitoring. The article describes the modification of network routing protocols for energy balancing in nodes, using the mobility of the coordinator node which provides dynamic network reconfiguration possibilities
