Improvising Network life time WSN using Mobile Data Aggregator

Abstract

Multi-hop, ad hoc, wireless sensor networks (WSNs) are considered a promising technology to change our physical environment and hence our life in this environment. WSNs are typically deployed using battery-powered stationary sensor nodes equipped with sensing, computing and wireless communicating modules. Sensors can be embedded into buildings or scattered into spaces to collect, process, store and send out relevant information for various civilian or military purposes.
When a data sink (e.g. a base station) is out of reach of a data source sensor node, they can rely on intermediate sensor nodes to relay data packets. Here battery-powered Wireless network is its extremely constrained source of energy supplied by batteries coming with sensor nodes, because sensor nodes are typically small and thus use tiny batteries
