A link error and malicious packet drops in 2 sources for packet losses in multi-hop wireless circumstantial network. we tend to observe that sequence of packet losses within the network, I fascinated by confirm whether or not the losses area unit caused by link errors solely, or by the combined result of link errors and malicious drop. I particularly fascinated by the insider-attack case, where...

We examine two special cases of the problem of optimal Linear Quadratic Gaussian control of a system whose state is being measured by sensors that communicate with the controller over packet-dropping links. We pose the problem as an information transmission problem. Using a separation principle, we decompose the problem into a standard LQR state-feedback controller design, along with an optimal...

Security is the major area of concern in communication channel. Security is very crucial in wireless sensor networks which are deployed in remote environments. Adversary can disrupt the communication within multi hop sensor networks by launching the attack. The common attacks which disrupt the communication of nodes are packet dropping, packet modification, packet fake routing, badmouthing atta...

The successful operation of the present Internet depends mainly upon TCP/IP which employs end-to-end congestion control mechanisms built in the end hosts. In order to further enhance this paradigm of end-to-end control the Random Early Detection algorithm has been proposed, which starts to mark or drop packets at the onset of congestion. The paper addresses issues related to the choice of queue...

Mobile Ad-hoc NETwork (MANET) is an application of wireless network with self-configuring mobile nodes. MANET does not require any fixed infrastructure. Its development never has any threshold range. Nodes in MANET can communicate with each other if and only if all the nodes are in the same range. This wide distribution of nodes makes MANET vulnerable to various attacks, packet dropping attack ...

Recently, a number of Active Queue Management (AQM) algorithms, such as REM and GREEN, have been proposed which reduce the packet queueing backlog and hence reduce the network’s latency close to the propagation delay. This paper uncovers a fundamental problem that a low latency TCP/IP network faces. We call this problem the “low latency efficiency collapse”. With Explicit Congestion Notificatio...

To solve the parameter sensitive issue of the traditional RED (random early detection) algorithm, an adaptive buffer management algorithm called PAFD (packet adaptive fair dropping) is proposed. This algorithm supports DiffServ (differentiated services) model of QoS (quality of service). In this algorithm, both of fairness and throughput are considered. The smooth buffer occupancy rate function...
