Comparative analysis of routing techniques in chord overlay network

Overlay networks are not a new field or area of study. This domain of computing will someday drive P2P systems in various application areas such as block-chain, energy trading, video multicasting, and distributed file storage. This study highlights the two widely known methods of routing information employed in one of such overlay networks called chord. In this study, simulations of both routing modes (iterative and recursive) and their variations under no-churn (leaving and joining of nodes) and churn conditions was carried out. The routing parameter (successor list size) was varied for each of the routing techniques in a simulation study. The results obtained show that semi recursive routing gives a better routing performance under churn scenarios.

Impact of Network Topology on Energy Efficiency in WSN

<p class="0abstractCxSpFirst"><span lang="EN-US">Wireless communication network has a significant success in scientific and industrial communities. Due to its various advantages, this technology is considered as a key element in current network architectures. It represents the architecture that allows to group a large number of sensors to collect information about a physical process in different environments. The gathered data is transmitted to base station which communicates the information to the end user.</span></p><p class="0abstractCxSpFirst">Several protocols are proposed for WSNs routing, by considering the limited capacities of sensor nodes according to a specific topology that allows to organize the nodes within the network. However, the performance of each routing protocol mainly depends on the application requirements and its results in terms of the lifetime of WSN and satisfaction of objectives defined.</p><p class="0abstractCxSpLast"><span lang="EN-US">According of the structure of WSN, the routing techniques can be divided in three types hierarchical, location-based flat routing. This paper, present the different routing techniques in WSN, based on the organization of nodes in sensor area. We focus specially to study the three types, cluster-based, chain-based and location-based routing techniques. These techniques will be simulated in order to compared their performances with our protocol Location-Based LEACH (LOC-LEACH).</span></p>

Design of Modified Tabu Search (MTS) Algorithm, an Optimization Technique for Intelligent Routing of an IOT Network with an aim to Improving the Efficiency

In this study, Modified Tabu Search (MTS) optimization technique with metaheuristic approach has been proposed. This technique is based on an example of salesman travelling problem that could be resolved effectively using metaheuristic Tabu Search algorithms where implementation of an intelligent routing technique has been proposed in order to improving the efficiency of an IOT network. Further, in this piece of research work, existing routing techniques have been studied to predict a cost-effective shortest path for different network size. It was observed that Modified Tabu Search (MTS) is quite an efficient technique in surpassing all existing routing techniques, and therefore, could prove to be one of the most preferable technique in a real time scenario to be applied to an IOT based network.
