Protected data transmission in cluster based Mobile Adhoc Networks (MANETs) is a challenging mission due to the high level of node mobility of nodes and resource constrained autonomous stations during packet routing. To target this mission, a Mobile Agent based QoS (MAQ) platform has been planned in this paper that uses an improved clustering algorithm during data communication. A Mobile agent architecture has been anticipated in a way that it is coupled with the cluster head of every cluster in MANET and when priority based real time application gets notified in these clusters then the proposed system gets activated to support prioritized service to these applications including checking and monitoring the flow characteristics for real time applications. JADE (Java Agent Development Environment) based prioritized scheme at the mobile agent has been implemented in the proposed system. As this is a function oriented approach, so the overall network performance significantly improves resulting better throughput and packet delivery ratio.

1. Introduction

In MANETs, there are some features which makes the network special. They include easy setup, infrastructure less organization, and with self- configurable nodes. These networks are basically applied in some specific applications such as battle field, medical applications etc. (Pati et al., 2016). Basic challenging factors in MANETS (Rout et al., 2015) are to handle the sustainability of network connection (Oh, 2009) with increasing scalability and ability to handle during maximum mobility of nodes (Rath et al., 2016). Similarly, there are many clustering algorithms (Umamaheswari and Radhamani, 2015) that supports cluster based routing (Rath and Pattanayak, 2014) in MANETs. Some of them use mobile agents for routing functions that are described in literature review section. The clustering algorithms basically structures the main network into some groups of nodes called clusters in a hierarchical manner (Derr and Manic, 2013). In this structure there is a cluster head which is selected among a group of stations with high level of resources such as high configuration with sufficient memory (Bridges and Vladimirova, 2013), high speed processor and located with approximately equal distant from other nodes of the group. Because of the changeability and unpredictable nature of the mobile ad-hoc networks (Sharma et al., 2015) due to wireless medium and dynamic mobility of nodes (Rath et al., 2016) there are certain issues which are to be handled carefully (Rath and Pattanayak, 2014). Resource utilization, Constant bandwidth provision, channel sharing, link failure and repair (Pattanayak et al., 2016) etc. some of the challenging issues which are taken care in the proposed protocol design.
