“…For example, when a node does not have information to send to the main station, an allocation technique activates to allocate the time assigned to the free node in the TDMA schedule to another node that has information to send. Thus, reducing energy and time consumption as well, as can be seen in Fig 11 [6].…”

Advances in the world of communications and information technology, as well as the urgent necessity to monitor particular areas and regions, have led to a considerable and influential development in the world of wireless sensor nodes. As they are small, low-cost multipurpose nodes with limited energy and capabilities. The most important points that deserve research and solution is the problem of energy conservation and increasing the lifetime of the network as a whole. Whereas, many routing protocols have been proposed in the wireless sensor network, some of which are based on homogenous networks while others are not, some are location-based, some are based on hierarchical orientation, some are based on the hybrid approach and many more. Despite the long time that has passed since the discovery and activation of the Low Energy Adaptive Clustering Hierarchy (LEACH) protocol, it and its descendants still have the lion's share of attention, research, and development. In this research, we will be presenting the most prominent routing protocols while pointing to some pros and cons of each protocol.

The LEACH protocol is a “standard” protocol used in the analysis and simulation of wireless sensor networks. This article analyzes the effect of varying parameter values in the LEACH protocol. In particular, the case of varying cluster head node assignments to , , and of the total nodes of the network. Specifically, it shows the energy effect of this variation and the corresponding data traffic analysis, showing simulation results that illustrate the behavior resulting from this variation by using an approach of time-division multiplexing on the clusters.

“…Figures 7, 8, 9 and 10 show the simulation of the state of art protocols that are ER-HEED [9], HEED [18], REECHD [7], RUHEED [8] and UHEED [23], FMUC [14] and M-LEACH [24] (i.e., multi-hop LEACH). These figures have on the X-axis the competition radius R 0 which varies from 20 meters to 70 meters and on the Y-axis the FND measure.…”

CER-CH: Combining Election and Routing Amongst Cluster Heads in Heterogeneous WSNs

Heterogeneous Wireless Sensor Networks (WSNs) are essential to the IoT vision. WSNs implement a virtual layer that can gather data about the real world. WSNs are composed of wireless battery powered devices that can have heterogeneous features related to computational power, memory, and communication capabilities. Because devices are battery powered, gathering data in an energy efficient way is crucial for the lifespan of the network. Clustering is a reasonable solution. This organises the devices into sets (clusters). Each cluster has a cluster head (CH) that gathers data from the nodes belonging to its cluster and communicates with other CHs in order to report data to a centralised base station (BS). This is usually achieved via a CH routing tree that is rooted at the BS. Beside clustering, the rotation in the role of CHs amongst the nodes of the network is a standard means to better distribute energy consumption. In this paper we propose a novel approach (CER-CH) where the CH routing tree definition and the CH rotation are combined together. More precisely, starting from any clustering criteria, we propose a novel rotation heuristic combined with a novel top-down CH routing tree definition in order to balance the node energy consumption and generate more energy efficient CH routing trees. Our experiments show that our rotation strategy enhances on average the network lifespan of 20% when compared to the state of art protocols.INDEX TERMS Heterogeneous wireless sensor networks, energy saving, routing.In this section we present two strategies for building the routing tree amongst cluster heads.
