Wireless Sensor Networks (WSNs) facilitate efficient and reliable monitoring of specified area for multiple applications. Variety of protocols are designed to increase the effectiveness and lifetime of WSNs. Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is one of them. LEACH is a hierarchical clustering based protocol where data is transferred to the data evaluation center through an intermediary...
A wireless sensing element network consists of hundred to thousands of little sensing element nodes that have restricted energy, all told forms of network Energy's attention is a {very important} issue and during this it is very important for planning protocols. This paper discusses the common cluster protocol and improve cluster head choice criteria. By LEACH protocol cluster head is chosen on random...
Wireless sensor networks are composed of hundreds or even thousands of sensor nodes which have limited energy. Energy consideration is a very critical issue for designing routing protocols. This paper discusses a common clustering protocol, called LEACH, and improves cluster-head selection criteria. LEACH selects cluster-heads based on random probability, while the proposed algorithm considers the...
There are several modification has been happened in LEACH protocol. Most of modifications are in cluster organization. This paper studies modified LEACH protocol using data update procedure of cluster head. In LEACH protocol frequency of sending data to the base station by smaller cluster is higher than bigger cluster due to that energy dissipation in smaller cluster is more than bigger cluster. This...
A large portion of energy-aware routing protocol for wireless sensor networks are cluster-based. In cluster based approach, energy at the cluster head nodes are drained more rapidly compared to other member nodes. Dynamically change cluster heads periodically could partialy mitigate this problem, but clusters that are far from base station still suffer from large amount of energy for directly transmit...
Hierarchical clustering algorithms are very important to increase the network's lifetime. In this paper we proposed Algorithm Routing Protocol based BCDCP and LEACH that called Inner Cluster Routing Protocol Wireless Sensor Network (ICRP), a new hierarchical clustering algorithm that have ability to create equal cluster with the same number of sensor like BCDCP method and then divided into small cluster...
Wireless sensor network protocols commonly use clustering to reduce the rate of energy dissipation in the system. With this technique, some nodes are selected as cluster heads and the remaining as member nodes so that cluster heads mainly use energy transmitting to the base station and member nodes transmitting to their cluster head. For the latter, the amount of energy used depends on the distance...
Cluster formation and cluster head selection are important problems in sensor network applications and can drastically affect the network's communication energy dissipation. However, selecting of the cluster head is not easy in different environments which may have different characteristics. In our previous work, in order to deal with this problem, we proposed a power reduction algorithm for sensor...
Coverage is one of the basic characteristics for wireless sensor networks. In this paper, we investigate the coverage preserving cluster head election technique. Sensors are optimally scheduled in different statuses between different rounds by genetic algorithm. A set of simulations is carried out. The simulation results show that, using the optimal schedule generated by genetic algorithm, our method...
Energy Efficient Routing is a crucial issue in Wireless sensor networks (WSNs). This paper proposes a novel algorithm, Parametric Protocol for Energy Efficient Cluster Head Selection (PPEECS) in WSN, which consists of two phases; Region formation phase and Cluster Head (CH) selection phase. In prior phase we divide the network into several regions depending upon node density distribution. The later...
There are many routing protocols and algorithms developed for data transmission in Wireless Sensor Network (WSN). The main objective of this paper is an increasing of performance and reduction of energy dissipation in WSN. In this paper, the Bacterial Evolutionary Algorithm (BEA) or Bacteriologic Algorithm (BA) is selected to compare performance with Genetic Algorithm (GA) and Low Energy Adaptive...
Wireless sensor networks (WSN) have been considered as a promising method for reliably monitoring both civil and military environments under hazardous or dangerous conditions. Due to such environments, the power supplies for sensors in the network are not usually rechargeable or replaceable. Therefore, the energy efficiency is critical for the lifetime and cost of WSN. Numerous mechanisms have been...
The optimal number of cluster heads is an important parameter of wireless sensor network performance. Network nodes will consume more energy if the number of cluster heads is too much or too little. This paper focuses on novel calculation method for optimal number of cluster heads. Base on the analysis of LEACH energy dissipation model, novel calculation method is derived from the total energy dissipation...
For wireless sensor networks (WSNs), it is a challenging task how to schedule the energy resource to extend the network lifetime due to the fact that WSNs are usually powered by limited and non-rechargeable battery. A clustering scheme is helpful in reducing the energy consumption by aggregating data at intermediate sensor nodes. In this paper, we propose a balanced parallel k-means based clustering...
This paper talk about the communication protocol named LEACH. The protocol focuses on reducing the power consumption of wireless sensor networks, which can have significant impact on the overall energy dissipation of these networks. LEACH uses localized coordination to enable scalability and robustness for dynamic networks, and incorporate data fusion into the routing protocol to reduce the amount...
Sensing coverage is an important issue for sensor networks, since it is viewed as one of the critical measures of performance offered by a sensor network. The design of a routing protocol is generally independent of the sensing coverage issue. Since some nodes may become invalid after they have used up their own energy resource, the achievable sensing coverage will gradually degrade as time passes...

Corresponding three general evaluation methods to evaluate the energy efficiency of the cluster-based routing protocols such as LEACH, PEGASIS, and BCDCP are provided. Moreover, three facts are...
