QALPA- An Efficient QoS Aware Hybrid Localization Model Using Particle Swarm Optimization and Ant Colony Optimization for Cognitive Wireless Sensor Networks

Abstract

A sensor network operates wirelessly and transmits detected information to the base station. The sensor is a small sized device, it is battery-powered with some electrical components, and the protocols should operate efficiently in such least resource availability. Here, we propose a novel improved framework in large scale applications where the huge numbers of sensors are distributed over an area. The designed protocol will address the issues that arise during its communication and give a consistent seamless communication system. The process of reasoning and learning in cognitive sensors guarantees data delivery in the network. Localization in Scarce and dense sensor networks is achieved by efficient cluster head election and route selection which are indeed based on cognition, improved Particle Swarm Optimization, and improved Ant Colony Optimization algorithms. Factors such as mobility, use of sensor buffer, power management, and defects in channels have been identified and solutions are presented in this research to build an accurate path based on the network context. The achieved results in extensive simulation prove that the proposed scheme outperforms ESNA, NETCRP, and GAECH algorithms in terms of Delay, Network lifetime, Energy consumption.

Grid-Based Design for Dual Monitoring Applications in WSN With Mobile Sink

“…For conserving energy many protocols including bioinspired algorithms like swarm intelligence have been designed [7]. Many routing protocols for saving energy and reliable data transmission wireless sensor networks for both delay tolerant and delay sensitive applications have been proposed previously [8]- [11]. But very few works like [12]- [14] can be applied to monitor both periodic data and events simultaneously.…”

Improved Quality of Services with Intelligent MAC in Wireless Sensor Networks for Mission Critical Applications

“…But when collision occurs bottleneck is created at intermediate node forming low PDR. The traditional 802.15.4 MAC is considered in our previous work [8] and [9] which created low performance of Qos in the network. This paper concentrated on designing a protocol which provides high energy efficiency and best quality of service be assigning the duty based on available power and avoiding the collisions by rotating the cluster head role based on the queue length.…”

“…The routing protocol PSO is used as same described in [9]. The proposed algorithm is compared with existing algorithms ESNA [8], QALPA [9]. Proposed IMAC outperforms existing algorithms QALPA and ESNA in terms of lifetime as shown in figure 3.…”

“…Wireless sensor networks (WSN) have been considered as keen role player in solving many real time applications where human reach is impossible. Hence WSN has gained tremendous interest for researcher to solve the problem of resource constraints [1]. These networks are composed of nodes called motes which transmit and receives sensed data to accomplish a mission.…”
