This paper proposes a simple path diversity algorithm (SPDA) for Interdomain routing. The SPDA uses source routing to find an alternate path from a source to a destination, and allows flexible division of traffic over the best and alternate path. The SPDA comprises three steps. First, the BGP protocol is extended to allow the BGP routing table to save the multiple paths for any destination. Second,...
In this paper, a new routing protocol, called traffic-aware and low-overhead routing protocol (TALORP) is proposed. The TALORP protocol, which is an enhancements of the low-overhead routing protocol (LORP), uses backup routes to mitigate the flooding problem that is frequently used to repair link failures. It also takes into account the traffic flows on different paths toward the destination in order...
In this paper, we propose an anycast mechanism which can adaptively choose the best next-hop to forward packets during the announcement traffic indication map (ATIM) window of multi-channel medium access control (MMAC) protocol. In order to improve the performance of networks by reducing transmission retries and packet drop probabilities, we also propose a multipath extension of AODV routing protocol...
In this paper we propose a set of different configurations of failure recovery schemes, developed for network-on-chip (NoC) based systems. These configurations exploit the fact that communication in NoCs tends to be partitioned and eventually localized. The failure recovery approach is based on checkpoint and rollback and is aimed towards fast recovery from system or application level failures. The...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
