A number of the practical scenarios relating to sensor networks are modeled as multi-objective optimization formulations where multiple desirable objectives compete with each other and the decision maker has to choose one of the tradeoff solutions. These multiple objectives may or may not conflict with each other. Keeping in view the nature of the application, the sensing scenario and input/output...
Distributed joint source-channel coding technique is finding its application in the ever evolving world of telecommunication, especially in the sensor network paradigm. The unique characteristics of the sensor networks are giving birth to new signal processing techniques and shifting the processing burden from the transmitter to the receiver side. The nodes of sensor networks, when deployed over particular...
The exchange of network state beacons (NSBs) is crucial to monitoring the dynamic state of MANETs like sensor networks. The rate of beacon exchange (FX) and the network state define both the time and nature of a proactive action to reconfigure the network in order to combat network performance degradation at a time of crisis. It is thus essential to select the FX within optimized bounds, so that minimal...
Proactive self-configuration is crucial for MANETs such as sensor networks, as these are often deployed in hostile environments and are ad hoc in nature. The dynamic architecture of the network is monitored by exchanging so-called network state beacons (NSBs) between key network nodes. The beacon exchange rate and the network state define both the time and nature of a proactive action to combat network...
