A Review: Clumping in Mobile Adhoc Networks

ABSTRACT: Mobile ad hoc networks (MANETs) consist of mobile devices that form the wireless networks without any fixed infrastructure or centralized administration. The infrastructure based cellular architecture sets up base stations to support the node mobility. Mapping the concepts of base stations into MANET leads to the design of logical clump, where the clump heads in every clump play the role of base station. Clumping in MANET is the virtual partitioning of the dynamic nodes into various groups. In this paper, we have proposed protocols and algorithms for efficient design of clumping in MANET. Closer Clump Detection Protocol (CCDP) has been designed to help the nodes to probe their immediate neighbours. Energy Based Clumping Algorithm (EBCA) has been proposed that uses the node mobility and its available battery power for calculating the node weights. A Broadcasting Range Adjustment Protocol (BRAP) has been proposed which allows the isolated nodes to adjust their ranges to remain connected with existing clump heads. Each of the work is evaluated separately to analyse their performances and compared with the competent results
