In this paper, we provide analyses performance of IEEE 802.11, 802.15.4 MAC and S-MAC protocols in terms of throughput, energy consumption and data packet delivery. Our simulation results show that S-MAC protocol with active and sleep cycle consumes energy less than about 10% and 15% compared to IEEE 802.15.4 and IEEE 802.11 MAC protocols respectively.

In this paper, we implement and analyses performance of multiple black hole attack nodes simultaneously in AODV routing protocol in terms of throughput, energy efficiency and data packet delivery. Our simulation results show that the more attackable nodes in network simultaneously, the lower the energy efficiency and network performance.

This paper highlights the distinction between cluster merging and cluster diffusion, presents architecture for carrying out efficient diffusion and finally compares these two approaches under various network conditions. Simulations are carried out in Network Simulator (NS2) which shows that cluster diffusion can be rendered efficient when multiple edge nodes are used for inter-cluster communication.

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.

In this paper, performance of Ad hoc on-Demand Distance Vector (AODV) Protocol and Dynamic Source Routing (DSR) protocol are evaluated in presence of wormhole attack and without wormhole attack with Constant Bit Rate (CBR) traffic under dissimilar scalable network mobility. Also we evaluate effect and compare it with standard protocol in term of Packet Delivery Ratio, throughput and End to End Delay via simulation, using Network Simulation2 (NS2) for our research.

This article proposes a valid route testing mechanism (VRTM) and integration of VRTM into AODV protocol to make DWAODV which is able to detect and prevent the wormhole attacks. Using Network Simulator (NS2), we evaluate the security effectiveness of DWAODV protocol on random movement network topology at high speed.
