Routing Protocol for MANET Based on QoS-Aware Service Composition with Dynamic Secured Broker Selection

Abstract

MANET is a mobile ad hoc network with many mobile nodes communicating without a centralized module. Infrastructure-less networks make it desirable for many researchers to publish and bind multimedia services. Each node in this infrastructure-less network acts as self-organizing and re-configurable. It allows services to deploy and attain from another node over the ad hoc network. The service composition aims to provide a user’s requirement by combining different atomic services based on non-functional QoS parameters such as reliability, availability, scalability, etc. To provide service composition in MANET is challenging because of the node mobility, link failure, and topology changes, so a traditional protocol will be sufficient to obtain real-time services from mobile nodes. In this paper, the ad hoc on-demand distance vector protocol (AODV) is used and analyzed based on MANET’s QoS (Quality of Service) metrics. The QoS metrics for MANET depends on delay, bandwidth, memory capacity, network load, and packet drop. The requester node and provider node broker acts as a composer for this MANET network. The authors propose a QoS-based Dynamic Secured Broker Selection architecture (QoSDSBS) for service composition in MANET, which uses a dynamic broker and provides a secure path selection based on QoS metrics. The proposed algorithm is simulated using Network Simulator (NS2) with 53 intermediate nodes and 35 mobile nodes of area 1000 m × 1000 m. The comparative results show that the proposed architecture outperforms, with standards, the AODV protocol and affords higher scalability and a reduced network load.

“…This helps to reach the optimal solution. The optimal location of the best agent is identified using Equation (7).…”

“…The MANET is an infrastructure-less network, which causes an extra overhead for maintaining the routing and changes in the network topology [6]. Moreover, the MANET has developed as a promising application for the Internet of Things (IoT), emergency communication, and disaster management [7]. The MANET is considered a highly promising solution in emergency and disaster management.…”

Research on Stability-Enhanced Clustering Algorithm Based on Distributed Node Status Judgment in MWSN

“…There are many clustering protocols developed for MWSN [6,8,16,[18][19][20][21][22][23]. The protocol design of hierarchical wireless sensor networks using the clustering method can be roughly divided into two main stages: the clustering phase and the communication phase.…”

“…In addition, the protocol has an expected threshold for the number of CHs in the network. Similarly, Rajakumar et al [19] also comprehensively consider various influencing factors in the network in order to select dynamic brokers, but the difference is that this scheme contains up to 10 parameters. Undoubtedly, such a scheme will bring substantial computational overhead to sensor networks.…”
