In recent years a flurry of research activity has produced many suggested schemes for clustering wireless sensor networks, but no hard numbers for real-world implementations. This lack of guidance for developers makes it very difficult to effectively and confidently build working networks. This paper partially addresses these concerns by deriving minimal timing bounds on the clustering process in...
The recent interest in Wireless Sensor Networks has led to a number of clustering algorithms that use the limited energy available at sensors more efficiently. In this article, we present a heritable clustering algorithm based on HEED for low energy wireless sensor network. It brings in appointment mechanism to reduce the cluster head reelect overhead efficiently. In the cluster, TDMA communication...
Clustering schemes improve energy efficiency of wireless sensor networks. The inclusion of mobility as a new criterion for the cluster creation and maintenance adds new challenges for these clustering schemes. Cluster formation and cluster head selection is done on a stochastic basis for most of the algorithms. In this paper we introduce a cluster formation and routing algorithm based on a mobility...
The most important issue in designing a data gathering algorithm is how to save energy of sensor nodes while meeting the requirement of application such as sensing are coverage. On the other hand, in the real applications, it is unrealistic to guarantee all sensors have the same energy because they have different energy consumption. In this paper, A cluster based data gathering protocol for heterogeneous...
Sensors have limited resources in terms of memory, energy and computational resources. Clustering has been proposed by researches to group a number of nodes to form a cluster that managed by cluster head. The advantage of this strategy is to minimize the number of message transmissions. In this paper, we propose clustering protocol called Centralized Dynamic Clustering CDC. Each cluster selects a...
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...
With recent development of wireless sensor network (WSN), it has led to the appearance of many application specific communication protocols which must be energy efficient. Among those protocols, LEACH (low energy adaptive clustering hierarchy) protocol is one of the most promising protocols. In this paper, we propose the geographical-based multihop clustering algorithm (GBMCA) based on LEACH, which...
