In sensor-network, enhancing network-lifetime is an essential concern due to “battery-constraints”. So maximize the duration of the network is considered as main objective while designing the algorithm. Some sensor nodes are nearer to the base-station and that nodes are burdened because they are doing a task to gather data of entire area and forward to the base-station. The tree structure is de...

Topology control is an efficiency method that can extend the network lifetime in a wireless sensor network. There are several researches involve the topology control problem. In this paper, we design an energy-efficient topology control algorithm both take into consider with topology construction and count infinity problem. In the topology construction, we build a reliable topology to reduce th...

Advances in medical sciences with other fields of science and technology is closely casual profound mutations in different branches of science and methods for providing medical services affect the lives of its descriptor. Wireless Body Area Network (WBAN) represents such a leap. Those networks excite new branches in the world of telemedicine. Small wireless sensors, to be quite precise and calc...

The authors propose three variants of distributed and stateless forwarding strategies for wireless sensor networks, namely greedy minimum energy consumption forwarding protocol (GMFP), lifetime maximising GMFP (LM-GMFP) and variance minimising GMFP (VAR-GMFP), which aim at maximising the network lifetime while achieving a high forwarding success rate. GMFP selects a forwarding node that minimis...

In wireless ad hoc networks, energy efficiency plays important role to improve the lifetime of network. Nodes in wireless ad hoc network are limited battery powered. Therefore, energy efficiency is of vital important in the wireless ad hoc network. Hence there is challenge to maximize the network lifetime. This paper presents a brief overview of wireless ad hoc network, causes of energy loss an...
