In this paper, we study the two different type of routing strategies used in wireless sensor networks i.e. proactive and reactive routing mechanisms. These routing mechanisms are applied in different kind of applications for efficient routing in the network. In this paper, we have studied the different routing protocols which use these routing mechanisms and have compared them. We have also taken the homogenous and heterogeneous type of networks and also see the effect of homogeneity and heterogeneity on the routing in the network. So, we have taken LEACH and SEP routing protocols for homogenous and heterogeneous network respectively using proactive mechanism for routing and TEEN and TADEEC protocols for homogenous and heterogeneous using reactive mechanisms. Lastly we have compared the results of two routing strategies in term of stability period (the round in which first node dies), lifetime of the network and throughput i.e. data send to the base station per unit round.

“…The sensor nodes inform the appropriate cluster heads that they will be a member of the cluster. Afterward, the cluster heads assign the time on which the sensor nodes can send data to the cluster heads based on a TDMA approach [4]. The cluster head establishes a transmission schedule for its cluster and transmits this schedule to each node in its cluster.…”

“…With slots of constant duration, time to send a frame of data depends on the number of nodes in the cluster. After a certain period of time spent on the steady-state phase, the network goes into the setup phase again and enters another round of selecting cluster heads [4].…”

Continuous advancement in wireless communication has enabled the deployment of wireless sensor networks for environment monitoring. The use of wireless sensor networks in this type of monitoring, it is very much difficult to replace the battery of the sensor node or replace whole sensor node once they deployed. So that development the different methodology to extend the lifetime of the sensor node is must.Low Energy Adaptive Clustering Hierarchy (LEACH) is cluster based routing protocol which provides life expectancy. In this paper proposed new routing protocol Energy Efficient Hybrid LEACH (EH-LEACH) in which the threshold criteria for selection of cluster head is changed and also consider residual energy of the sensor node. The simulation results clearly indicate that proposed approach is very much energy efficient as compared to LEACH. Also EH-LEACH is sustaining his properties while varying node density. Optimization of cluster based hierarchical routing protocols is required for Better Operations. General TermsTwo ray model, Cluster head selection algorithm, Steady state phase, Threshold Criteria,Sensor nodes.

:-Contemporary growths in the field of microelectronics and network communications which make it achievable to organize in a wide range of Wireless sensor network. These sensor networks have recently come into prominence because they have hold the potential to revolutionize many segments. As we know that wireless sensor network suffers from excessive packet loss, over hearing, retransmission of the packet due to node mobility and constant energy dissipation. Routing protocol techniques is one of the research area in wireless sensor network. So by crafting an efficient routing algorithm to improve the network lifetime. In this paper, we are drawing a new technique for cluster-head selection by analyzing the lasting energy of the node and also considering the type of communication between the nodes and cluster-head. This technique is compared with the conventional LEACH. The work is simulated in M ATLAB, and the result will shows increasing in the network lifetime by increasing the number of alive node and decreasing the number of dead node. Keywords-WSN, LEACH, lifetime, hard-threshold, soft-threshold, lasting energy.__________________________________________________*****_________________________________________________ I. INTRO DUCTIONWireless sensor network is a network consisting of several number of ho mogeneous nodes named as sensors nodes which are spatially disseminated all over the locality. It also includes sensor nodes, sink node and management node, large nu mber of sensor nodes are deployed in the monitored area, creating a network through the way of self-organizing. These networks are used to monitor physical or environmental conditions such as temp, pressure, sound, vibration at these locations. Wireless communicat ion empowers the co-operation of nodes to fulfill bigger tasks that sole node cannot. Nodes in WSN are densely organized and are greater in numbers as compared to mobile ad hoc networks. These nodes sense the vibration and gather all the information and communicate with each other and pass informat ion along fro m one to each other fro m source to base station. [1] . Recent encroachment in micro-electro-mechanical system (M EM S) technology, digital electronics and wireless communicat ion had enabled the imp rovement of low-power, low-cost, mu lti-functional sensor nodes that are small in size, and communicate released in short distance. A sensor network is subject to a unique set of reserve constraints such as finite on-board battery power and limited network co mmun ication bandwidth. In the typical sensor network, each sensor nodes operates released and has a microprocessor and a s mall amount of memo ry for signal processing and task scheduling. Each sensor node communicates wirelessly with a few other local nodes within its radio co mmunication range.[2]WSN have enormous potential because they expand human ability to monitor and interact remotely with the physical world. Smart sensors are able to co llect enormous amount of previously unknown data, which have the way for a n...
