In wireless sensor networks (WSNs), clustering-based algorithms have been proved to be effective techniques to save energy and improve fault tolerance. In this paper, a scale-free evolving model for clustering-based WSNs with exponential growth behavior is presented, in which the nodes arrive as a Poisson process with rate λ. This model takes into account four types of evolving events: selectio...

This paper discusses advantages of LEACH Algorithm and the existing improved model which takes the famous hierarchy clustering routing protocol LEACH Algorithm as researching object. Then the paper indicates the problem that in the algorithm capacity factor of cluster head node is not taken into account leading the structure of clusters to be not so reasonable. This research discusses an energy...

This paper deals with the problem of tracking a radio controlled vehicle (RCV) fitted with LED’s moving within a wireless sensor network (WSN). The WSN test bed is made up of a number of Mica2 motes with fixed and know locations and equipped with light sensors. To reduce the overload of communications, power consumption, and allow for scalability, the network is divided into clusters, where mem...

Mobile Wireless Sensor Networks (MWSN) consists of nodes that are small sized and of mobile nature. Since nodes are mobile the energy drains out is continuous offering short duration networks and hence energy efficiency and network life time are still the major hurdles for efficient communication network. Literature indicates that Clustering is the most popular solution for energy efficient rou...

The efficient use of energy source in a sensor node is most desirable criteria for prolong the life time of wireless sensor network. In this paper, we propose a two layer hierarchical routing protocol called Cluster Based Hierarchical Routing Protocol (CBHRP). We introduce a new concept called head-set, consists of one active cluster head and some other associate cluster heads within a cluster....

In terms of the characteristics of itself node number, density and topology dynamic change in wireless sensor network, according to the wireless transmission energy consumption model REDM, Load-balanced Hierarchical Topology Control Algorithm based on LEACH algorithm is designed. The algorithm still uses the concept of ”round”. Substitute cluster head and load evaluation method are introduced i...

The cluster-based routing protocols are most accepted to improve the network lifetime and to reduce the energy consumption of wireless sensor network. This paper presents the pollination based optimization algorithm also called OLEACH-C to improve the performance of LEACH-C protocol. The PBO algorithm is used for clustering in WSN. The node that has maximum remaining energy will be selected as ...

In coding theory, a channel coding algorithm is good if it achieves the Shannon capacity [1]. Similarly, we seek to derive a universal curve against which we can measure how good (or bad) a variable topology routing protocol (e.g. for ad-hoc networks) performs, in comparison with a theoretical minimum routing overhead, which is the amount of information needed to describe the changes in a dynam...

This paper presents a novel clustering protocol, the Decentralized Energy Efficient cluster Propagation (DEEP) protocol, that manages the communication of data while minimizing energy consumption across sensor networks. The paper also presents an Inter-Cluster Routing protocol (ICR) that is compatible with the proposed clustering technique. The proposed clustering protocol uses the unique techn...

In this paper, a wireless cognitive radio sensor network is considered, where each sensor node is equipped with cognitive radio. As energy consumption is the main problem when using sensors therefore a new clustering algorithm is developed according to which group of nodes form cluster having a single cluster head. Each cluster has balanced energy which prolongs overall lifetime of CRSN. Cluste...
