Wireless sensor network is defined as the network composed of tiny and energy restricted sensor nodes. Sensor nodes collect the useful information from surrounding environment and deliver it to the base station. Sensor nodes have limited energy. Routing protocols must consume minimum energy in order to prolong the network lifetime. Clustering is most energy efficient technique. LEACH is one of ...

Wireless Sensors Networks (WSNs) have a big application in heterogeneous networks. In this paper, we propose and evaluate Advanced Low-Energy Adaptive Clustering Hierarchy (Ad-LEACH) which is static clustering based heterogeneous routing protocol. The complete network field is first divided into static clusters and then in each cluster separate Ad-LEACH protocol is applied. Our proposed protoco...

Wireless sensor networks are extensively used in different fields, including severe and harsh environments such as battlegrounds, volcanic areas, healthcare, so on. The major constraint of WSNs is the limited power supply, which impacts lifecycle entire network. Clustering a performing method to optimize consumption extend lifetime WSNs. LEACH considered first classical clustering protocol ener...

In order to overcome the energy loss involved by communications in wireless sensor networks (WSN), the use of clustering has proven to be effective. In this paper, we proposed a dynamic centralized genetic algorithm (GA)-based clustering approach to optimize the clustering configuration (cluster heads and cluster members) to limit node energy consumption. The obtained simulation results show th...

Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...

revision): Sep 9, 2012 In order to gather information more efficiently, wireless sensor networks (WSNs) are partitioned into clusters. Most proposed clustering algorithms do not consider the location of the base station. This situation causes hot spot problems in multi-hop WSNs. In this paper, we analyze a fuzzy clustering algorithm (FCA) which aims to prolong the lifetime of WSNs. This algorit...

Do simulation comparisons among classical clustering algorithm LEACH, AODV Algorithm of the existing ZigBee Routing Protocol and this clustering routing algorithm. Simulation results show...

This paper proposed a wireless sensor network routing protocol base on ant colony principle and LEACH protocol with energy prediction. The new algorithm added the factor of energy in the procedure that ants had been searching the optimal path. Cluster-head sent data to sink by multiple hops transmission. Therefore, the new algorithm reduced cluster-heads energy consumption. In order to avoid ro...
