This article aims to secure a routing mechanism by completing amendments in previously proposed efficient secure routing (ESR) protocols against networking layer attacks in mesh networking environments. Along with generating the tickets to prove the authenticity of communicating clients, each node proves the legitimacy of its succeeding node by computing the behaviour. The intermediate nodes selected for routing the data packets proves the legitimacy of each other by getting the passive acknowledgement process within a predefined time to live (TTL) time. Further, grey hole and black hole attacks are considered in the network simulation environment as they drastically affect the network metrics during the communication because of their severe attacking characteristics. The proposed mechanism is validated over conventional routing mechanisms against packet loss and network delay parameters in the presence of black hole and grey hole routing attacks.

Voice Packets

Factors like network delay, latency and bandwidth significantly affect the quality of communication using Voice over Internet Protocol. The use of jitter buffer at the receiving end compensates the effect of varying network delay up to some extent. But the extra buffer delay given for each packet plays a major role in playing late packets and thereby improving voice quality. As the buffer delay increases packet loss rate decreases, which in general is a very good sign. However, an increase of buffer delay beyond a certain limit affects the interactive quality of voice communication. In this paper, we propose a statistical framework for adaptive playout scheduling of voice packets based on network statistics, packet loss rate and availability of packets in the buffer. Experimental results show that the proposed model allocates optimal buffer delay with the lowest packet loss rate when compared with other algorithms.

Automatic grouting is a very important part in the well drilling process. The stability of grouting system is one of the factors affecting the drilling accident. This paper presents a automatic grouting method based on network control system. In order to find out the influence on the control performance after using network in the system, paper sets up the system model with the simulation toolbox TrueTime-2.0 of MATLAB and separately studies the influence on the control effect by network delay and data packet loss according to the simulation result. The results prove that both the network delay and data packet loss all make great differences on the control performance of system, so we need to take appropriate strategies to reduce the influence in the actual designs.

Currently applications in wireless sensor network are just designed in the laboratory networks, while in real networks the resource is not unlimited because of network bandwidth, delay, jitter, packet loss and so on. In this paper, we propose a simulator and emulator for network delay and jitter in wireless sensor network, which is designed with FPGA and DDR3 to achieve the wire-speed delay/jitter simulation. The experiment results show that the simulator/emulator is efficient.
