routing loop is detrimental to an IP network, because the IP packet will neverend up at the correct location. A field in the IP frame called the Time-To-Livefield will prevent IP packets from traversing the networks forever, but the resultwill be a disgruntled end user. A tunnel, on th[r]

Cisco routers are able to implement filtering, compression, prioritization,and policing (dedicating network capacity). Except for filtering, thesecapabilities are referred to collectively as QoS.Although QoS is wonderful, it is not the only way to address bandwidthshortage. Cisco espou[r]

Energy efficient routing protocols are consistently cited as efficient solutions for Wireless Sensor Networks (WSNs) routing. The area of WSNs is one of the emerging and fast growing fields which brought low cost, low power and multifunctional sensor nodes. In this paper, we examine some protocols r[r]
