A Review: Novel Protocol for Clumping in Mobile Ad hoc Networks

ABSTRACT: Mobile ad hoc networks (MANETs) is the combination of three words 1. Mobile(Movable or Transportable) 2. Adhoc( Temporary or for specific purpose) 3. Networks(Flexib le data applications which use networks to communicate) o r A MANET can be defined as a system of autonomous mobile nodes that communicate over wireless lin ks without bounded, defined or fixed infrastructure. MANETs are useful in places that have no communicat ions infrastructure. Mobile adhoc network is a type of ad hoc network that can change locations and configure itself on the fly. Base station plays a very important role in infrastructure based cellular networks . But to create a base station in infrastructure less network is very difficult b ecause of movable of nodes. Mapping the logic of base stations into mobile ad hoc networks leads to the design of logical clu mp, where the ch(clu mp head) in every clu mp play the role of base station. So clu mping is very important in this type of networks . The aim of this research work is to enhance the network lifetime , proper balancing the power consumption among mobile nodes and increase the throughput of the networks. For this type of architecture we have design some protocols and algorithms which a re : Closer Clu mp Detection Protocol (CCDP) , Energy Efficient Based Clu mping Algorith m (EEBCA ) and A Broadcasting Range Adjustment Protocol (BRAP) has been proposed which allo ws the isolated nodes to adjust their ranges to remain connected with existing c lu mp heads. Each of the work is evaluated separately to analyze their perfo rmances and compared with the co mpetent results. KEYWORDS: MANET, Clu mping, Clu mp head, CCDP, EEBCA, BRAP. I. INTRO DUCTION A Mobile Adhoc Network is a group of mobile nodes that can communicate to each other with out any fixed base station . The mobile nodes that are in clu mp range of each other can directly co mmunicate, whereas others needs the aid of intermediate nodes to route their packets. Each of the node has a wireless interface to commun icate with each other. These networks are fully distributed, and can work at any p lace without the help of any fixed infrastructure as access points or base stations
