Recent developments in low-power communication and signal processing technologies have led to the extensive implementation of wireless sensor networks (WSNs). In a WSN environment, cluster formation and cluster head (CH) selection consume significant energy. Typically, the CH is chosen probabilistically, without considering the real-time factors such as the remaining energy, number of clusters, distance, location, and number of functional nodes to boost network lifetime. Based on the real-time issues, different strategies must be incorporated to design a generic protocol suited for applications such as environment and health monitoring, animal tracking, and home automation. Elementary protocols such as LEACH and centralized-LEACH are well proven, but gradually limitations evolved due to increasing desire and need for proper modification over time. Since the selection of CHs has always been an important criterion for clustered networks, this paper overviews the modifications in the threshold value of CH selection in the network. With the evolution of bio-inspired algorithms, the CH selection has also been enhanced considering the behavior of the network. This paper includes a brief description of LEACH-based and bio-inspired protocols, their pros and cons, assumptions, and the criteria of CH selection. Finally, the performance factors such as longevity, scalability, and packet delivery ratio of various protocols are compared and discussed.

“…The proposed model is divided into two main phases at the first setup phase and at the second steady state phase. In the first phase nodes are spread randomly allover network area and cluster heads should be elected randomly [21,22]. The selection of cluster head in the setup phase of the proposed model is presented in Figure 3.…”

Wireless sensor networks have strict constrains in size, weight and energy. The conflict of long lifetime and strict energy constrain brings a natural integration of energy harvesting into wireless sensor networks. A modified low energy adaptive clustering hierarchy (LEACH) protocol has been proposed to increase the network life time. Modified LEACH is divided into two main phases at the first setup phase and at the second steady state phase. Setup phase has been modified such that cluster head (CH) selection will be selected only from advanced nodes. Results showed significant improvement in WSN overall lifetime. Simulations show number of dead nodes vs rounds. Comparison between pure LEACH and modified one showed significant improvement in lifetime, also comparison between modified LEACH and multi-path multi-hop energy efficient routing protocol shows significant improvement in performance.

INTRODUCTIONWith the advancement in smaller scale integrated circuit technology, Wireless Sensor Networks (WSNs) have begun to assume an essential part in our every day lives. It is a direct result of the lessening in cost of the sensor nodes, prompting expanding arrangements of WSNs to a larger degree. Potential applications for wireless sensor networks exist in an assortment of fields, including mechanical process checking and control, condition and living space observing, machine wellbeing checking, home automation, human services applications, atomic reactor control, fire recognition, question following and traffic control. Effective outline and usage of wireless sensor networks have turned into a hot zone of research as of late, because of the huge limit of sensor networks to empower applications associating the physical world with the virtual world. Like living beings, an assortment of current devices and types of gear depends on the sensory information from this present reality around it. These sensory data comes is given by Wireless Sensor Networks (WSN), which includes a couple of minor sensor nodes to screen physical or natural conditions, for instance, temperature, vibration, weight, sound or development, and subsequently aggregately send these information to a central figuring structure, called the base station or sink. Diverse routing protocols administer the development of this data. Broadly the routing protocols can be named level based routing, various leveled based routing, and area based routing. Filter (Low Energy Adaptive Clustering Hierarchy) is a various leveled based routing protocol which utilizes irregular revolution of the nodes required to be the bunch heads to equitably convey energy utilization in the network. Sensor network protocols are very straightforward and consequently are exceptionally helpless to assaults like Sinkhole assault, Selective sending, Sybil assault, Wormholes, HELLO surge assault, Acknowledgment parodying, adjusting, replaying routing data. For instance, Selective sending and HELLO surge assault influences networks with grouping based protocols like LEACH.
