Abstract

Implanted biomedical sensor networks provide a major application of sensor networks in the near future. Their high temperature due to wireless communication, might damage the surrounding tissues. This paper presents an efficient thermal-aware routing. Our proposed protocol states that when some nodes in the shortest path have a high temperature, ignores this path. The simulation results indicate the superiority of the proposed method compared to other thermal-aware routing protocols in terms of reducing temperature without a significant increase in packet delivery delay and power consumption of nodes. © 2009 IEEE

Abstract

Knowing the capabilities of game theory in analyzing environment consisting of many decisionmakers or agents, it has been the goal of many researchers to apply Game Theory analyses in computer and telecommunication networks. One of the main subjects in the networks based on the viewpoint of Game Theory is routing problems in special networks. In this paper, routing in Wireless Mesh Networks, which are growing and developing rapidly, is studied as an example for routing in computer and telecommunication networks and a new model for such networks is proposed based on Non-cooperative Game Theory. It is proposed to solve this model by a heuristic method essentially based on simulated annealing...

Abstract

This research presents an efficient thermal-aware routing protocol based on Shortest Hop Routing algorithms for implanted bi medical sensor network. Implanted biomedical sensor networks provide a major application of sensor networks in the near future. These in-vivo sensor nodes collect desired biometric data and communicate the data wirelessly to a base-station through a multi-hop network. They generate the heat due to wireless communication and circuitry power consumption. A high temperature of the in-vivo nodes for a prolonged period might damage the surrounding tissues. Most of the protocols for sensor networks don’t take the thermal issue as a factor in the routing of packets. In its...

Managing Old and Obsolete Knowledge: Exploring the Pattern of Unlearning Actions Based on Different Knowledge Types, The Case of Iranian Software Industry

, Ph.D. Dissertation Sharif University of Technology Rezazade Mehrizi, Mohammad Hossein (Author) ; Ghasemzadeh, Fereidoun (Supervisor) ; Kermanshah, Ali ($item.subfieldsMap.e)

Abstract

The rapid technological changes have faced organizations with a new challenge: old and obsolete knowledge when it hampers organizational change or creates some kind of possible negative impact. Hence, in many cases, companies need to actively deal with such old and obsolete knowledge and their possible negative impacts in order to survive in highly competitive market. Defining unlearning as the intentional process of managing the old and obsolete knowledge in order to reduce its possible negative impacts, this study focuses on how organizations manage their old and obsolete knowledge and how the pattern of unlearning actions varies based on different types of knowledge.
Analyzing the...
