  • It is expected that many networks will be providing services at a time in near future and those will also produce different interfering signals for the current Slotted ALOHA based systems. A random packet destruction Denial of Service (DoS) attacking signal can shut down the Slotted ALOHA based networks easily. Therefore, to keep up the services of Slotted ALOHA based systems by enhancing the secured operating regions in the presence of the interfering signals from other wireless systems and DoS attacking signals is an important issue and is investigated in this paper.

  • It is well known that neighbor discovery is a critical component of proactive routing protocols in wireless ad hoc networks. However there is no formal study on the performance of proposed neighbor discovery mechanisms. This paper provides a detailed model of key performance metrics of neighbor discovery algorithms, such as node degree and the distribution of the distance to symmetric neighbors. The model accounts for the dynamics of neighbor discovery as well as node density, mobility, radio and interference.

  • The proposed scheme was compared with the randomized approach. The different parameters such as number of address conflicts, average end to end delay, average throughput, control load are analyzed and a comparison is made between two protocols. Results from the simulation experiments show that ID based addressing scheme outperforms randomized approach in all the metrics evaluatednumber of address collisions, average throughput, average end to end delay and normalized routing load.

  • In Mobile Ad-hoc Network (MANET) is a Self-configuring network of mobile routers (and associated hosts) connected by wireless links. This MANET forms a random topology and routers move randomly free. Topology changes rapidly and unpredictably .Nowadays we are using so many protocols for maximizing the network bandwidth but, we can not attain the best throughout using protocols in MANET.

  • In this paper we propose an adaptive congestion control algorithm using cross layer design, which out-performs even during constrained situation. For analyzing the performance we have chosen four popular routing protocols such as AODV, DSR, DSDV and TORA. We also observe through simulation in NS2 that AODV out-performs other routing protocols in normal situation and DSR out-performs in constraint environment.

  • Energy Efficient Load Balanced (EFLBAODV) and compared it to the traditionally existing reactive routing protocol Ad Hoc on Demand Distance Vector (AODV) thus using the load balancing technique to improve the node to node communication in our network. Also our routing protocol will be energy efficient as it will minimize the communication time and overheads thus utilizing the energy resources. Some important metrics like route discovery time, route errors, MAC delay, network load, end-to-end delay and throughput have been taken to evaluate the overall improvement in the novel protocol.

  • In the other hand, SIP protocol, which knows a huge booming in internet networks, requires centralized entities, like proxy server, registrar server and location service; consequently SIP is not adapted to Ad Hoc networks. We have presented in a new technique VNSIP (Virtual Network for Session Initiation Protocol) to fix the problem related to constraints of SIP deployment in MANET (Mobile Ad Hoc Networks). In this paper we use a new algorithm which we have called MCAC (MANET Call Admission Control) to improve VNSIP Performances.
