“…Low energy adaptive clustering hierarchy (LEACH) [17], [18] is a low energy adaptive clustering protocol that deploys network nodes into multiple clusters, each cluster is managed by a CH. With the advantage of the LEACH is that no information of network configuration or data from the sink is needed once determinative the CH.…”

Today, science and technology is developing, particularly the internet of things (IoT), there is an increasing demand in the sensor field to serve the requirements of individuals within modern life. Wireless sensor networks (WSNs) was created to assist us to modernize our lives, saving labor, avoid dangers, and that bring high efficiency at work. There are many various routing protocols accustomed to increase the ability efficiency and network lifetime. However, network systems with one settled sink frequently endure from a hot spots issue since hubs close sinks take a lot of vitality to forward information amid the transmission method. In this paper, the authors proposed combining the colony optimization algorithm ant colony optimization (ACO) routing algorithm and mobile sink to deal with that drawback and extend the network life. The simulation results on MATLAB show that the proposed protocol has far better performance than studies within the same field.

This paper proposes an adaptive hierarchical MAC protocol (AH-MAC) with cross-layer optimization for low-rate and large-scale wireless sensor networks. The main goal of the proposed protocol is to combine the strengths of LEACH and IEEE 802.15.4 while offsetting their weaknesses. The predetermined cluster heads are supported with an energy harvesting circuit, while the normal nodes are battery-operated. To prolong the network’s operational lifetime, the proposed protocol transfers most of the network’s activities to the cluster heads while minimizing the node’s activity. Some of the main features of this protocol include energy efficiency, self-configurability, scalability, and self-healing. The simulation results showed great improvement of the AH-MAC over LEACH protocol in terms of energy consumption and throughput. AH-MAC consumes eight times less energy while improving throughput via acknowledgment support.

“…In comparison with normal nodes, these nodes may be configured with more memory and more powerful microprocessor/microcontroller. There are three types of resource heterogeneity [1] in WSNs: computational, link and energy heterogeneity. The main impact of the heterogeneous WSNs [18] is increasing network lifetime, reliability in data transmission and reducing latency.…”

In this paper we have proposed different models and implementation of different energy efficiency protocols in Wireless Sensor Networks (WSN). We have analyzed as well as optimized the performance of the heterogenous LEACH protocol for different parameters. In this paper, the proposed models have been applied on the n-node network and the performance of the same has been calculated and shown with the help of results. Analysis of heterogenous LEACH simulation network is done. Performance of a clustering protocol is also determined by duration of stable and unstable period. Network Lifetime of Heterogeneous LEACH Protocol for €_ft1=1is much stable. Result prove that energy consumption remains almost same until the death of first node and after that it starts decreasing. In SEP cluster head of advance node is frequent become the cluster head than the normal node.Instablity period of SEP has reduced from that in heterogeneous LEACH and there is also improvement in stability period. With decrease in number of nodes, packets transmission reduces. Throughput is improved as; consumption per round in SEP. energy consumption has reduced in case of SEP than that in LEACH and Heterogeneous LEACH.
