Automatic recognition of parts is an important problem in many industrial applications. One model of the problem is: Given a nite set of polygonal parts, use a set of \width" measurements taken by a parallel-jaw gripper to determine which part is present. We study the problem of computing e cient strategies (\grasp plans"), with the goal to minimize the number of measurements necessary in the w...

Fischer, Lynch, and Paterson showed in a fundamental paper that achieving a distributed agreement is impossible in the presence of one faulty processor. This result was later extended by Moran and Wolfstahl who showed that it holds for any task with a connected input graph and a disconnected decision graph. In this paper we extend that latter result, and in fact we set an exact borderline betwe...

Today, one of the new technologies in the modern era is Vehicular Ad-hoc Network which has takenenormous attention in the recent years. Because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called V2V orvehicle to vehicle communication and vehicle to roadside infrastructure, called V2I. Designin...

In this paper, we describe a RAT (radio access technology) agnostic approach referred to as OMMA (Opportunistic Multi-MAC Aggregation) that can aggregate multiple RATs operating over independent spectral bands. Aggregation and/or traffic shaping is performed above the air interface protocol stacks but below the IP layer. We investigate the problem of minimizing the average packet latency (the s...

Wireless body Area networks (WBANs) include a number of sensor nodes placed inside or on the human body to improve patient health and quality of life. Ensuring the transfer and receipt of data in sensitive data is a very important issue. Routing algorithms should support a variety of service quality such as reliability and delay in sending and receiving data. Loss of information or excessive da...
