Clustering and relaying techniques are important approaches towards mitigating the problem of finite network lifetime in wireless sensor networks. To this end, given a clustered wireless sensor network (WSN) (with defined cluster heads and their associated clusters) and a given relay node placement, we present a distributed service allocation algorithm for the relay node for maximizing network lifetime...
Clustering is used extensively in wireless sensor networks to optimize lifetime. Within clustering, the optimization of cluster head (CH) location is critical since CHs consume energy faster and have greater influence on lifetime than non cluster head (NCH) sensors. Energy harvesting wireless sensor networks (EH-WSNs) use energy harvesting devices to harvest energy from environment. In contrast with...
Underwater Wireless Sensor Networks (UWSNs) are expected to support a variety of civilian and military applications. Sensed data can only be interpreted meaningfully when referenced to the location of the sensor, making localization an important problem. In terrestrial WSNs, this can be achieved through a series of message exchanges (via RF communications) between each sensor and Global Positioning...
