Abstract
This paper presents a novel approach to analyse the traffic efficiency of infrastructureless networks. Wireless communication is rapidly moving towards more infrastructureless routing schemes, where the devices encounter frequent topology changes and communicate with each other anonymously and sporadically. Nodes do not have the opportunity to choose an optimum routing path, they do rather obtain a valid routing path on the fly during the data exchange by cooperating with the nearest neighbours. Packets emanated from an infrastructureless node are disseminated through each node found in the vicinity. This produces a vast number of packet duplicates within the entire communication environment, causing the problem of increased congestion, increased packet delay, more packet drops, and undesirable energy consumption compared to the infrastructured networks. Data exchange and packet routing operations in large networks are highly stochastic. Thus, the performance analysis of routing operations is modeled as a stochastic queueing system, where the input and output traffics and throughput operations of routing systems are precisely formulated in the form of stochastic processes. A hypothetical routing algorithm is also defined here as a reference model in order to perform a comparative analysis of the infrastructureless routing scheme.
Highlights
T HE WIDESPREAD use of Internet of Things (IoT) and mobile ad-hoc networks is rapidly growing with immense complexity, where routing is performed independent of any communication infrastructure
Even though challenges are great, we are deeply motivated to initiate a research investigating whether the traffic efficiency of infrastructureless networks can be accurately modelled, if so, can we apply the model to performing numerical analysis of the network traffic in a reasonable manner?
We have collected some data from a small set of nodes, 8 access points and 24 client nodes communicating with the wireless access points, and used the data to justify the simulation results
Summary
T HE WIDESPREAD use of Internet of Things (IoT) and mobile ad-hoc networks is rapidly growing with immense complexity, where routing is performed independent of any communication infrastructure. Since the nodes of infrastructureless networks flood all unknown packets to all adjacent channels within the communication range, the adjacent nodes receive duplicates of flooded data packets leading to increased traffic congestion, more energy consumption, frequent power interruptions, and path losses These problems are encountered more frequently when the number of nodes and the geographical distances among the nodes increase unduly. It is a fact that a wide spectrum of mobile wireless devices and applications are connected together via public networks in an ad–hoc manner Through this conglomerate structure users require secure and reliable data exchange, while some operations demand an efficient coordination of critical communication tasks such as public protection, disaster relief, and remote data gathering and reconnaissance tasks for critical operations (e.g., ambulatory services, disaster control systems, and anti-terror operations).
