Fuzzy-Based Channel Selection for Location Oriented Services in Multichannel VCPS Environments

Abstract

Abstract-Recently, location-oriented services in Vehicular Cyber-Physical System (VCPS) have witnessed significant attention due to their potentiality to address traffic related issues towards on-road safety and efficiency. The multichannel communication aids these services by tuning their overall performance in vehicular environments. The literature on multichannel communication is based on interference as channel quality measure. However, uncertain mobility and density of vehicles significantly affect channel quality apart from interference. The static quantification of channel quality is not suitable due to the dynamic characteristics of the channel quality parameters. In this context, this paper proposes Fuzzy-based Channel Selection framework for location-oriented services in Multichannel VCPS environments (F-CSMV). Specifically, a system model is presented for deriving channel access delay using Markov chain model. The channel quality is estimated using channel access delay (CAD) and signal-to-interference ratio (SIR). The fuzzy logic based channel selection framework is developed focusing on fuzzification and defuzzification of CAD and SIR. The comparative performance evaluation attests the benefit of the framework as compared to the state-of-the-art techniques considering channel and network performance-related metrics in VCPS environments.

“…Once delay aware procedure is called, it selects only those nodes belonging to NNL-QUAL, whose end-to-end path delay (PD i,j ) is less than or equal to required delay (PD req ), and places them in NNPD (lines: 10-12). In the case of empty NNPD, the data packet is discarded immediately (lines: [13][14]. If there is a single node in NNPD, then that node is selected as DH (lines: [15][16].…”

“…e IoT enables the things/objects in the environment to actively participant using internet. at is, they share data and information with other members or stack holders through wireless/wired networks, often using the same internet protocol (IP) that connects the Internet [12,13]. In this way, the things/objects are capable of recognizing actions and deviations in their surroundings and are capable of acting/reacting autonomously largely without human intervention in an appropriate way.…”

Transmission Capacity Characterization in VANETs with Enhanced Distributed Channel Access

“…Some new protocols have designed and proposed for traffic safety data dissemination. In Reference [12], inter vehicle distance is analyzed within connectivity aware routing design for data dissemination. Additionally, in Reference [13], a channel selection framework for location-oriented services in VANET is proposed.…”

An adaptive interference‐aware and traffic‐aware channel assignment strategy for backhaul networks

“…Therefore, the proposed scheme assumes that all MRs are equipped with at least two radios and the total radios are greater than available channels in number. The WMNs involve planned placement of MRs as compared to ad‐hoc networks; therefore, it is implicit that MRs are static and generally do not alter the topology . However, the exception for addition of new MRs or failure of existing MRs is automatically dealt due to the self‐healing characteristic of WMNs.…”
