During the last decade, Wireless Sensor Networks (WSNs) have emerged and matured at such point that currently support several applications like environment control, intelligent bu...
—Mobile sink has been adopted by many schemes for lifetime improvement in wireless sensor networks. It is necessary to propagate the topological or location changes caused by the...
- Mobile sinks can be a viable solution to solve the problem that energy consumption is not balanced for all the sensor nodes in Wireless Sensor Networks (WSNs). Frequent location ...
In contention-based sensor networks, nodes compete to access a shared channel for data transmission and collision is a common challenge. For power conservation, periodical active/s...
