Trustworthy Data Transmission For Immensely Aggressive Mobile Ad Hoc Networks

Abstract

Trustworthy data delivery in highly dynamic mobile ad hoc networks (MANETs) is an essential issue in wireless networks. Most current routing protocols for MANETs agonize from consistent and well-timed delivery of data. To combat this problem, a Geographical Routing (GR) protocol and a Greedy Forwarding protocol based on position (GFBP), has been proposed to take advantage of greedy forwarding and transmission nature of wireless network. Any of the neighbour nodes overheard the transmission as a data packet is sent out will act as forwarding candidates and will take a turn to forward the packet if it is not relayed within a given time by the same best forwarder then the sub-forwarder will allow the candidates to forward the packet and thus ensure data trustworthiness. To increase the visibility of the GFBP and combat communication hole, a Bare Handling (BH) scheme based on Virtual Destination is proposed. Here to attain the destination, the packets are reconnected.. Both the simulation and theoretical results show that under high node mobility, GFBP will lead to substantial changes in packet distribution ratios.
