A novel application on the recently emerging Personal Communication Services (PCS) networks is the multimedia communication. In this paper; we evaluate multimedia communications capability of one of the PCS standards, Personal Access Communications System's (PACS) packet channel (PPC) using simulation modeling. The performance of PPC's slot aggregation and data-sense multiple access techniques are studied by considering the downlii and uplink in a single cell and combined uplink/ downhnk in two cells and changing various parameters such as the number of users and certain protocol parameters.Interconnection of PPC with the Internet is discussed next. Frame rates of MPEG-1 coded images transmitted in a PACS cell as IP datagrams are determined. Handover characteristics of PPC downlink are studied by changing different parameters such as the cell size, the speed of the mobile host and time between handovers. The results clearly establish that multimedia communication on PPC is only feasible at lower bandwidths and frame rates and only a few users per cell can be supported. Careful tuning of PPC protocol parameters are required. There is one parameter whose variation gives opposite results on the downlink and uplink.

A Local/Global Strategy Based on Signal Strength for Message Routing in Wireless Mobile Ad-hoc Networks

Route switching is an important issue to connectionoriented communication that needs to maintain a route for a certain period. This paper suggests a new approach to ease the route switching problems in a network with higher migration rate of hosts. By monitoring the signal strength of messages, a host in a route that receives an incoming message can detect possible route fluctuations locally. As the average signal strength declines into a dangerous level, the host that receives the message will send an advance-warning message to the route source host. If the source host can find more stable routes locally, it will adapt a substitute route and will complete the process of adaptation before the breakdown of the original route actually occurs. If the route source host cannot adapt a new route locally, the source host will be forced to search for a new route by considering the entire network.
