To ensure uninterrupted communication in a mobile ad-hoc network, efficient route discovery is crucial when nodes move and/or fail. Hence, protocols such as Dynamic Source Routing (DSR) precompute alternate routes before a node moves and/or fails. In this paper, we modify the way these alternate routes are maintained and used in DSR, and show that these modifications permit more efficient route...

We have calculated, quantitatively, the time decay of donor-acceptor pair luminescence in compensated semiconductors, incorporating the effect of the potential fluctuations which exist in such materials. We show that the often-reported stretched-exponential decay law can here be derived rigorously, but only to a very close approximation, and, moreover, only provided that there is an alternate, ...

Due to the way BGP paths are distributed over iBGP sessions inside an Autonomous System (AS), a BGP withdraw that follows a failure may be propagated outside the AS although other routers of the AS know a valid alternate path. This causes transient losses of connectivity and contributes to the propagation of a large number of unnecessary BGP messages. In this paper, we show, based on RouteViews...

Mobile ad hoc network (MANET) is characterized as a dynamic, multi-hop wireless self-organized distributed ad hoc network. Because of node mobility and power limitation, the network topology changes frequently which leads to path breakage. Hence a dynamic routing protocol is required for ad hoc networks to function properly. Reactive on -demand routing protocols becomes very popular because it ...

This paper presents a comparison of critical loads for trusses, calculated by linear and nonlinear stability analysis. Analyses are provided by using finite elements method. In linear case, critical load is extracted from derived algebraic eigenvalue problem. In case of nonlinear analysis, critical load is determined by construction of postbuckling equilibrium path. Numerical examples for chara...

Mobile Ad hoc Networks are typically characterized by high mobility and frequent link failures. As a result, routing algorithms selecting a single path during route creation have to make frequent route discoveries resulting in decreased throughput and high endto-end delay. Multipath routing approaches like AOMDV make use of pre-computed routes determined during route discovery. This solution, h...

This paper proposes an autonomous inspection method for steel box girders that uses a wall-climbing robot instead of human workers. According to the 3D operating environment inside girder, path traverse positions be inspected. The comprises two alternate sections lane’s centerline and U-shaped steering. To realize robot’s tracking desired path, kinematics analysis based on different poses durin...

A central theme in previous studies of heading judgements has been whether the retinal flow field can be decomposed to recover the translation component of locomotion when flow also contains the effects of gaze rotation. We explored not just the effect of moving gaze, but also moving attention away from the locomotor path by presenting the case of fixating a road sign and completing different a...
