Efficient Routing Algorithm for Delay Tolerant Networks: Human Mobility based Spray and Wait Routing Protocol - Softcover

Inhaltsangabe

A Delay Tolerant Networks (DTNs), also known as intermittently connected wireless mobile networks, works effectively at the time of discontinuous network connectivity between two nodes. A communication network which is capable of storing packets momentarily in intermediate nodes and conveys the packets when end-to-end route is re-established or regenerated is known as a delay tolerant network/ disruption tolerant networks. Many routing protocols have been developed for DTN based on movement pattern of the nodes. In this book we presents a novel routing protocol which exploits mobility characteristics of human walk. We evaluate a novel Human Mobility based Spray & Wait Routing protocol (HMSaW) under human mobility as per Truncated Levy Walk (TLW) mobility model. HMSaW is more efficient compared to existing Spray and Wait routing protocol for mode movements as per human walk. The presented HMSaW protocol perform better in terms of delivery ratio and communication overhead compared to existing spray and wait Routing protocol with marginal reduction in delivery delay. MATLAB code of the presented simulation results are also provided in this book.
