Guaranteeing secure transmission in time critical networks through dual sense multiple control channel protocol

Abstract

The emergence of proper reservation techniques to acquire the channel in Mobile Ad hoc Network is main concern when there is a random, unstipulated and insecure communication. The denial of proper channel causes the foe nodes to cause virtual jamming, thereby preventing the legitimate nodes to communicate especially in the real time scenario where the time factor is very critical. To avoid this, a proper architecture along with a specialized medium access method is necessary. The method employed here is to use a hierarchical-like network forming subworkgroups that define clusters of nodes formed randomly. These clusters propose their own way to allocate the channels for the specific nodes at both the intra-level and inter-level. Also a specialized MAC protocol, Dual Tone Multiple Control Channel [DSMCL] protocol has been formulated based on the busy tone protocol. This protocol also ensures the Quality of Service which reduces the overhead of the upper layers. The mobile nodes follow their own routing protocols for forwarding of packets within the domain and redistribute them for interoperability. While the inter-level channel acquisition is by means of allocation/relocation algorithms, at the intra level, they are carried out using the CTSP (Cell/Technology Selection Problem) pattern. This ensures that a genuine node ready to communicate is not trapped by the malicious node communicating with them forever.
