Tadl-v2: An improved trust-aware dynamic location-based adaptation protocol for discovering multiple paths in MANETs

Mobile ad hoc networks (MANETs) have a numberof features that make the provisioning of QoS particularlychallenging to achieve. One of the challenging issues is how tofind reliable paths to deliver higher priority traffic in a highmobility network and do so with minimum overhead costs. Thispaper describes the design and evaluation of a multiple pathdiscovery protocol, called an improved Trust-Aware DynamicLocation-based (TADL-V2) protocol. TADL-V2 investigates howto minimize the production of control packet while discoveringthe optimal number of paths in a high mobility network. Theprotocol adjusts the number of control packets poured into thenetwork in response to the underlying network mobility level.It switches between two multi-path discovery methods while inthe same time increasing the searching area in adaptation to thenetwork mobility level. TADL-V2 is evaluated, using simulation,against the TADL protocol, the most relevant work, under variousnetwork conditions. The simulation study shows that TADL-V2outperforms TADL in terms of reducing routing overheads whenthe network is highly mobile. This overhead reduction can havea positive effect on QoS provisioning making the TADL-V2 moreeffective and efficient in providing QoS.
