An Enhanced Method of Secured Energy - Efficient Data Communication in MANET for Emergency Rescue Operation

Abstract

Mobile Adhoc Network (MANET) is a self configuring network consists of number of mobile nodes which can move in any direction at any time. The MANET is implemented for providing several applications such as border security, emergency rescue operation and business meetings, etc. Data communication between the mobile nodes in wireless environment mainly depends on life time of battery and storage capacity of mobile nodes. This paper presents about design of routing algorithms in order to provide data communication not only energy efficient but also secured. Three methods named Energy Optimized Node Partitioned Cluster Routing (EONPCR), Energy - efficient Polynomial Time Resource Channelized (EE-PTRC) framework and Secured QoS routing and Data Delivery method are proposed. The EO-NPCR method reduces routing delay by identifying appropriate neighbourhood nodes using Neighbourhood Sector-based energy conservation model. The EE-PTRC framework uses Two Hop Propagate Bandwidth Allocation model for reducing the bandwidth consumption also it improves data delivery. The third method named Secured QoS Routing and Data Delivery (SQR-DD) framework provides data communication over secured path also satisfying the QoS, it applies Geo-optimized maximum likelihood routing. The result of three methods is to achieve secured data communication in emergency rescue application by enhancing energy - efficient routing.
