Wireless sensor networks are an emerging technology for monitoring physical world. The energy constraint of Wireless sensor networks makes energy saving and Prolonging the network lifetime become the most important goals of various routing protocols. Clustering is a key technique used to extend the lifetime of a sensor network by reducing energy consumption. Also Putting few heterogeneous nodes in wireless sensor network is an effective way to increase the network lifetime and stability. The energy saving schemes for homogeneous wireless sensor networks do not perform efficiently when applied to heterogeneous wireless sensor networks. Thus, Energy efficient clustering protocols should be designed for the characteristic of heterogeneous wireless sensor networks. This paper surveys different energy efficient clustering protocols for heterogeneous wireless sensor networks and compares these protocols on various points like, location awareness, clustering method, heterogeneity level and clustering Attributes.

In this paper, the enhancement of HEED protocol to support mobility in both homogenous and heterogeneous network [Homogeneous HEED (H-HEED), two-, three-level heterogeneous (2H-HHED & 3H-HEED) and multi-level heterogeneous HEED (MH-HEED)] has been presented. Here, we have examined the performance of HEED, 2H-HEED, 3H-HEED and MH-HEED with random mobility in wireless sensor network in terms of stability, energy efficiency, lifetime and throughput. The results establish that the MH-HEED in sensor network proved to be superior because of the enhancement in the performance metrics like: stability, lifetime and throughput (data packets transmitted to BS) with the random mobility of BS. The network performance is dominating in terms of stability, throughput and energy efficiency if 3H-HEED protocol is used and it is useful for habitat monitoring and other similar applications. The overall performance of the network substantially improved in case of BS mobility.

Wireless Sensor Networks (WSNs) comprise of a large number of sensor nodes. These sensor nodes have limited energy resources, processing and storage capabilities. The network layer protocols have thus to ensure reliable communication under these conditions. A higher network lifetime is one of the key issues of WSNs. Clustering is a very basic topological concept that cuts down the energy expenditure in WSNs. At present, majority of research is directed towards a homogeneous environment, wherein all the sensor nodes have initially the same amount of energy. Contrary to this, in a heterogeneous environment, a certain population of the sensor nodes is furnished with additional energy resources, thus leading to an energy-hierarchy. This heterogeneity in the sensor nodes results in a higher network lifetime. In this paper, we have proposed an energy efficient clustering scheme called ETDEEC (Enhanced Threshold Distributed Energy Efficient Clustering). Simulation results demonstrate the protocol performs better in terms of network lifetime and packet delivery capacity as compared to others.

ABSTARCT: Wireless sensor network consists of thousands of sensor nodes which sense the environment and send the sensed data to the sink node. There exist many algorithms for routing in wireless sensor networks. In cluster based routing algorithms the clusters are formed and in each cluster one sensor node is selected as cluster head which collects data from other sensor nodes (cluster members) and further forwards data to the sink node. The energy efficiency of the protocol and network lifetime can be increased with node heterogeneity where few nodes are provided with extra capability like energy. In this paper we have surveyed various heterogeneous clustering protocols for wireless sensor networks and compared with various parameters like level of heterogeneity, criteria of CH selection, intra cluster topology, data transfer from CH to base station (sink node).

Abstract—Wireless Sensor Networks (WSNs) contain numer-ous sensor nodes having limited power resource, which report sensed data to the Base Station (BS) that requires high energy usage. Many routing protocols have been proposed in this regard achieving energy efficiency in heterogeneous scenarios. However, every protocol is not suitable for heterogeneous WSNs. Efficiency of protocol degrades while changing the heterogeneity parameters. In this paper, we first test Distributed Energy-

ABSTRACT- Due to their rapid and promising development, Wireless Sensor Networks (WSNs) have been predicted to invade all domains in our daily life in the near future. However in order to reach their maturity, researchers must find solution to some difficulties which are slowing down the wide spread use of these networks. Wireless sensor network comprise resource sensor nodes that are used to sense the environment, transmit the data to base station for further processing. Only cluster head is used for gathering data from each cluster and transmit that data to base station. Due to unbalancing in clustering process result, thereby causing packet loss, network lifetime, degradation of quality of services metrics. In this study we propose a token bucket algorithm technique that is used to increase the mobility and heterogeneity of the nodes to detect the congestion in network. The experimental result demonstrate that TBACCC achieved better performance in term of data transmission to base station, network lifetime and other quality of services metrics compared with priority based application specific congestion control clustering.
