Pervasive computing with voice application service must be providing unprecedented levels of technology in order to adapt the continually changed computing resources in ubiquitous environment. A number of conditions differ from the speech signal over IP network with heterogeneous devices while voice traffic is transported by packet-based in ubiquitous environment. In this paper, voice signals in packet...
In this paper, we present a novel congestion control algorithm (HRC), which uses hop-by-hop approach and rate-based transmission, for IEEE 802.11 multihop wireless networks. Since medium contention is most dominant cause of packet loss in multihop wireless networks, our algorithm considers the degree of medium contention level experienced at a given node for data rate control at the transport layer...
