In the energy-constrained wireless sensor networks (WSNs), clustering is an efficient technique to minimize the energy consumption of the sensor nodes. But, the clustering algorithms for WSNs with a static sink frequently suffers from uneven energy consumption problems, where cluster heads (CHs) further away from sink consume more energy in a single hop communication, with the CHs sending its data...
A large class of Wireless Sensor Networks applications involved in monitoring environmental parameters in isolated urban areas covered with sensor nodes. Mobile sinks are mounted upon isolated urban areas with fixed trajectories to monitor environmental parameters. These MS provides ideal infrastructure for retrieving sensory data from isolated WSNfields. The existing approach uses the multi-hop technique...
Wireless sensor networks (WSNs) with one static sink often suffer from energy hole problem, which means energy consumption of certain sensors near the sink or on critical path is much faster than other sensor nodes. Finally, network partition and isolated nodes are caused. To solve this problem, we propose an Energy-Efficient Strategy Enhancing Lifetime for WSNs based on MECA and PEGASIS. This algorithm...
In a ad hoc sensor networks node mobility would make clustering very challenging since the node membership will dynamically change, forcing clusters to evolve over time. In this paper, a novel distributed clustering approach is proposed for a long-lived ad hoc sensor networks. This work presents a protocol that periodically selects cluster heads according to a hybrid of the node mobility and node...
Sensor deployment problem is one of the important problems in Wireless Sensor Networks (WSN) since it represents the first phase that most of the network operations depends on. Sensor deployment strategies can be classified into two classes which are deterministic and autonomous (random) deployment. In the deterministic deployment, the deployment field is assumed accessible as well as the number of...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
