As sensor mobility becomes more and more universal, Wireless Sensor Network (WSN) configurations that utilize such mobility will become the norm. We consider the problem of maximizing the lifetime of a wireless connection between a transmitter and a receiver using mobile relays. Initially, all relays are positioned arbitrarily on the line between the transmitter and the receiver and have arbitrary...
To many sensor networks, the robust operation dependson deploying relays to ensure wireless coverage. This paperconsiders the crucial problem of optimal relay placement for wirelesssensor networks in indoor environments. The placement of relaysis essential for ensuring communication quality and data collection.A number of existing algorithms have been proposed forensuring full sensing coverage and...
Overlay network architectures that use orthogonal channels have been known to provide effective additional resources to underlying networks in high demand. Overlays are composed of relay nodes provided with rich computational resources and multiple wireless interfaces that make them capable of establishing several non-interfering networks. These networks can be used to move traffic around in a non-interfering...
