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

Sanjay Kumar, Dr.Sudhir Kumar Rathi

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(Flexible data applications which use networks to communicate) or A MANET can be defined as a system of autonomous mobile nodes that communicate over wireless links 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 because of movable of nodes. Mapping the logic of base stations into mobile ad hoc networks leads to the design of logical clump, where the ch(clump head) in every clump play the role of base station. So clumping 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 Clump Detection Protocol (CCDP) , Energy Efficient Based Clumping Algorithm (EEBCA) and A Broadcasting Range Adjustment Protocol (BRAP) has been proposed which allows the isolated nodes to adjust their ranges to remain connected with existing c lump heads. Each of the work is evaluated separately to analyze their performances and compared with the competent results.
