Multilayer Clustered Designing Algorithm is exploited to present MCDA - Hot Spot algorithm; a technique to increase the network throughput by alleviating the impact of hotspot issue on network lifetime. The network nodes in the hot spot region are in a flat layer form in contrast to rest of the network nodes that are grouped into clusters. This design substantially helps in achieving goal above. This...
In a Wireless Sensor Network (WSN), there are a large number of nodes whose power supply and computational capability are limited. The nodes in a wireless sensor network can be fixed or move randomly. Thus in these networks, to forward a data packet from one node to another needs to use specific strategies with very different characteristics. Accordingly the data forwarding strategy among nodes plays...
To improve the performances of wireless sensor network (WSN) and its lifetime, the management of power consumption and the energy harvesting is crucial.

With EH2M, each sensor node can adjust its duty-cycle dynamically by computing...
The underwater wireless remote sensors convey messages in a range, where there is no possible human intervention. It is difficult to replace the battery in order to sustain energy in an acoustic environment. Moreover, considering the environment, solar energy cannot be used to recharge for batteries. These sensors are required to be awake for an extended period, taking in consideration that they have...
