Wireless networking has witnessed an explosion of interest from consumers in recent years for its applications in mobile and personal communication. Energy efficiency is also an important design consideration due to the limited battery life of wireless node. In order to maximize the network life time and to minimize energy consumption, instead of routing through shortest path we propose routing...

In this paper we discuss the threat of malware targeted at extracting information about the relationships in a real-world social network as well as characteristic information about the individuals in the network, which we dub Stealing Reality. We present Stealing Reality (SR), explain why it differs from traditional types of network attacks, and discuss why its impact is significantly more dang...

A recent study characterizing failures in computer networks shows that transient single element (node/link) failures are the dominant failures in large communication networks like the Internet. Thus, having the routing paths globally recomputed on a failure does not pay off since the failed element recovers fairly quickly, and the recomputed routing paths need to be discarded. In this paper, we...

One of the ambitions when designing the Stream Control Transmission Protocol was to o er a robust transfer of tra c between hosts. For this reason SCTP was designed to support multihoming, which presumes the possibility to set up several paths between the same hosts in the same session. If the primary path between a source machine and a destination machine breaks down, the tra c may still be se...

Recently, several fully distributed (localized) location-based routing protocols for a mobile ad hoc network were reported in literature. They are variations of directional (DIR), geographic distance (GEDIR) or progress-based (MFR) routing methods. In DIR methods, each node A (the source or intermediate node) transmits a message m to several neighbors whose direction is closest to the direction...

In this paper we present a comparative study of two schemes to provide survivability for guaranteed QoS connections in a possible Next Generation Internet network architecture. In the first scheme a QoS connection is provided standby backup resources on a disjoint path by reserving resources on both the working and backup path. In order to reduce the amount of backup resources required a method...

Thermal expansion of a member can affect structural bearing capacity when one or more members are subjected to fire. To explore the developmental rule internal force in latticed shell structure, computation method sensitivity is presented based on alternate path method. Taking K8 single-layer structure as analysis object, finite element models established by ANSYS, applying temperature loads ra...

An algorithmic solution method is presented for the problem of autonomous robot motion in completely unknown environments. Our approach is based on the alternate execution of two fundamental processes: map building and navigation. In the former, range measures are collected through the robot exteroceptive sensors and processed in order to build a local representation of the surrounding area. Th...

Path problems were basically studied to find an alternate path that is, finding a second shortest route, if the route is blocked. The problem mainly focused on paths between vertices of given network. A new variant quickest problem, where predetermined data sent from source sink. flow relaxes limitations single multiple paths. In this paper we reviewed and problem. Later on, each clarified with...

-In MWSN, security is one of the main constrain for transmission of data in network, in existing system arises drawback in security area of WSN. We implement the protocol named secure distributed reprogramming protocol (SDRP) for efficient transaction; it has limited bandwidth support of data (1.6Ghz) transmission in network. It also suitable only for homogenous network, SDRP is implemented in ...
