Wireless Sensor Networks (WSNs) is one of the most rapidly evolving scientific domain, which is mainly due to the development of advanced small and low-cost sensor nodes with capability of sensing various types of physical and environmental conditions, data processing, and wireless communication. WSNs have many sensor nodes which have restricted battery power and these nodes have to transmit se...

-Wireless Sensor Networks (WSN’s) have become an important and challenging research area in last year. Wireless Sensor Networks consisting of nodes with limited power are deployed to gather useful information from the field. In WSNs it is critical to collect the information in an energy efficient manner. Ant Colony Optimization, a swarm intelligence based optimization technique, is widely used ...

Wireless sensor networks (WSNs) play a very important role in the Internet of Things. But, how to save the energy of the wireless sensor nodes and prolong the lifetime of such networks is an emergent task for the wide adoption of the networks. Considering the characteristics of wireless sensor nodes where energy consumption for transmitting data is much more than that for computation, this pape...

The field of communications networks continues to emerge, thus leading to the rapid growth in the field of wireless sensor networks (WSNs). WSNs are noticeably different from traditional Ad hoc networks. The conspicuous difference between WSNs and traditional Ad hoc networks is that they (WSNs) are strictly constrained by limited supply of energy, capacity of storage, power of computation, and ...

Heterogeneous Wireless Sensor Network (WSN) comprises of sensor nodes with distinctive capability, for example, diverse computing power and sensing range. Contrasted with homogeneous WSN, arrangement and topology control are more perplexing in heterogeneous WSN. Distinctive energy efficient clustering protocols for wireless sensor networks systems and thinks about these protocols on a few focus...

In this dissertation, we study data collection and its achievable network capacity in Wireless Sensor Networks (WSNs). Firstly, we investigate the data collection issue in dualradio multi-channel WSNs under the protocol interference model. We propose a multi-path scheduling algorithm for snapshot data collection, which has a tighter capacity bound than the existing best result, and a novel cont...
