Clustering sensor nodes is an effective topology control for increasing network lifetime and scalability. It also, balances the load on the sensor nodes. HEED is a well known distributed clustering protocol that uses both energy and communication cost to elect Cluster Heads (CHs) in a probabilistic way. This paper improves HEED protocol using fuzzy logic and a non probabilistic approach for CH election...
Scalable routing in wireless sensor network (WSN) is required for future applications to provide high-quality and robust transmission. In this paper we propose a Polychromatic Sets based scalable Routing (PSR) scheme for WSNs. PSR is a hierarchical routing scheme designed to scale to the network size. This scheme firstly partitions the network into multiple clusters which are organized as a multilevel...
Power Line Communication Networks (PLCN) represent a very attractive communication system which can be used for many applications in the area of both home/building automation and street lighting control. The main problem is how to organize the many nodes, in order to implement a network where all nodes can exchange information with a master node. In this paper a tree-based clustering approach is introduced...
In WSNs' application, the reduction of energy consumption and the entire network's lifetime should be optimized and feasible communications are must be ensured. All of the above have become to be an important factor to evaluate the performance of routing protocols. In the paper, we present a feasible routing protocol for WSNs in coal mine. Here, we call it LEACH-mine. In the algorithm, the cluster...
Since sensor nodes in wireless sensor networks (WSNs) are always randomly distributed, it is hard to cluster the network with balanced load, especially for the environment where sensor nodes' locations are easily changed. In this paper, we introduce a new scheme named dynamic clustering algorithm with balanced load (DCBL). It can not only cluster the network into a topology with balanced load and...
To satisfying expected coverage degree of application, we derived the smallest active node number K through node active-sleep theory. We also achieved intra-cluster active nodes scheduling algorithm. In data gathering protocol, this algorithm can make vast intra-member nodes obtain sleep, reduce data delay, lighten cluster head burden. The simulated experiment shows that the result of the algorithm...
