location service mechanism; instead, the location information is disseminated along with the route discovery control messages. As there exist no single unicast single path or multi-path/ multicast routing protocol that can simultaneously minimize the number of route discoveries as well[r]

for MANETs. In the last few years, a number of researchers have focused their attention on this issue. While the energy consumption problem has been widely considered in wireless sensor networks, mobile ad-hoc networks present a completely different set of constraints to[r]

Step 2 On each router, configure a loopback interface with a unique IP address. Cisco routers use the highest loopback IP address as the OSPF Router ID. In the absence of a loopback interface, the router uses the highest IP address among its active interfaces, which might force a router to ch[r]

guess like all technologies that succeed they seem to appear sponta-neously and quickly expand. The truth of the Internet and packet switch-ing in particular is that it has actually been around for a long time,30 years (or more). The reality is that email actually first appeared in1972. TCP/IP[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]
