Abstract: Mobile Adhoc Networks (MANETs) are expected to provide certain levels of Quality newlineof Service (QoS) under varying wireless channel capacity and noise constraints. These newlinenoisy and varying channel conditions make it difficult to provide reliable and efficient newlinereal-time communication in MANETs. The traditional approach of network security newlinecan t be applied to MANETs owing to its unique characteristics and constraints such newlineas topology instability and nodes mobility etc. With this view in mind decentralized newlinegroup key management has been taken into consideration, wherein, three techniques newlinehave been explored to achieve better utilization of Mobile Adhoc Networks under newlinevarying channel conditions: Address allocation for MANET merge and partition, newlineFault tolerance in topology, Group key Security issue.Addressing of nodes in MANET is of significant importance. In fact, the nodes need newlineto be assigned conflict free IP addresses especially when two or more clusters merge. newlineUnlike infrastructure based networks, MANET works on the concept of autonomous newlineand spontaneous networking and therefore the nodes in MANET must do selforganization newlineand self-configuration. A unique Election Algorithm has been proposed newlinethat computes the weight of each node within the cluster and the node with highest newlineweight is elected as cluster head. The results obtained thereof indicate that utilizing coordination among the nodes in newlineMANETs leads to better throughput and energy efficiency for the network while newlinemaintaining acceptable packet delay as imposed by the application, even in the newlinepresence of relatively high channel error rates. A method of utilizing different channel newlinecapacities has also been proposed that enables an individual network user to select the newlineappropriate delay-throughput trade-off for multi-hop routing in MANETs. newline
