Overlapped hierarchical clusters routing protocol for improving quality of service

Abstract

The rapid development in communications and sensors technologies make wireless sensor networks (WSNs) as essential key in several advanced applications such as internet of things (IoT). The increasing demands on using WSNs required high quality of services (QoS) because most WSNs applications have critical requirements. This work aims to offer a routing protocol to improve the QoS in WSNs, taking in consideration its ability to prolong the lifetime of the network, optimize the utilization of the limited bandwidth available, and decrease the latency that accompanies the packets transmitted to the gateway. The proposed protocol is called overlapped hierarchical cluster routing protocol (OHCRP). OHCRP is compared with the traditional routing protocols such as SPEED, and THVR. The results show that OHCRP reduces latency effectively and achieve high energy conservation, which lead to increase the network lifetime and insure network availability.

A trust based secure access control using authentication mechanism for interoperability in internet of things

“…Hence to overcome these attacks, a secure routing protocols must be developed to avoid attacks and eliminate malicious nodes from the network. The improvement of quality of service (QoS) parameters such as latency, delivery of packets, resource utilization and so on, can also enhance the networks routing [23], [24]. Some of the existing researches based on IoT interoperability are described as: Anuradha et al [25] developed a system to predict cancer using the internet of things to test whether blood results were normal or abnormal by improving security enhancement and authentication in the cloud area.…”
