Problem statement:The continuous increasing capacity of the cellular networks motivates the development of multiparty applications, such as interactive mobile TV and mobile social networks. For these environments, security group services are required. A practical way to provide security services is by using cryptographic methods. However, the key management needed for these methods, which considers a dynamic group membership, introduces a high communication and storage overheads. Approach: In this study we propose an efficient group key management scheme suitable for cellular networks. Results: Our scheme reduces the number of keys to be transmitted and to be stored at a mobile host in the presence of membership changes. The scheme is based on a two tier structure to organize the cells in areas and the mobile hosts in clusters within an area. The main objective of the two tier structure is to dissociate, in an advantageous manner, the mobile hosts' distribution from the topological network. Conclusion: Our approach offers security services to a large number of mobile hosts by using lower cryptographic resources, thus providing us a more efficient key updating process.

Problem statement: Effective Topology control will improve the performance and the capacity of Mobile Ad-hoc networks by building reliable network structure. Approach: Power level is used as the basis for topology control since it reduces spatial interference while increasing the effective channel capacity and network lifetime. Results: In this study, we design a topology control using efficient power management algorithm using clustering. In this study, initially the cluster-head is selected based on the factors power level, stability and connectivity. Then, the connectivity of each node of the cluster with the cluster-head is checked. If the connectivity is less than a minimum connectivity threshold, then it is increased by increasing the power level. If the connectivity is higher than a maximum threshold, then the cluster-head reduces its power level. Conclusion/Recommendations: By simulation results, we show that the proposed topology control algorithm outperforms existing topology control algorithms in terms of by increased node life time and reduced power consumption.
