Simulation of cordless communication systems

The performance of digital cordless telephones (CTs), currently being developed in the UK, is examined using a computer simulation. This shows the effect of using two different dynamic channel assignment strategies on performance over different operating ranges and user densities

A Water Management Support System for Amman Zarqa Basin in Jordan

A Water Management Support System for Amman Zarqa Basin in Jordan has been developed. The water management support system employs the Water Evaluation and Planning system (WEAP). The water resources and demands in the basin were modeled as a network of supply and demand nodes connected by links. The model was calibrated for the year 2005 data and then validated for the year 2006 data. Validation results showed good agreement between calculated and measured inflows to wastewater treatment plants in the basin. The model was run for the year 2005 data as well as for four scenarios for the year 2025 which are Business As Usual (BAU) scenario, Advanced Wastewater Treatment (AWWT) scenario, the Red Sea, Dead Sea Channel (RSDSC) scenario and the optimistic scenario. The BAU scenario assumes that water use trends for the year 2025 follows predictable trends, the implementation of the disi project and the Wehda dam are main components of the BAU scenario. The AWWT scenario assumes that the effluent of As Samra wastewater treatment plant is treated to a level where it can be used for unrestricted irrigation within the basin and in the highlands. The main component of the RSDSC scenario is the implementation of the RSDSC project. The optimistic scenario combines both the AWWT scenario and the RSDSC scenario. The AWWT scenario, the RSDSC scenario, and the optimistic scenario are child scenarios of the BAU scenario. The results showed that neither domestic demand nor agricultural demand is met for the year 2005. The results also showed that domestic and industrial demands can be satisfied for all the considered scenarios by proper management of the available resources. However, agricultural demand can’t be satisfied for the business as usual scenario.     

Dynamic channel allocation schemes for cordless telephones

A comparison is made between the traffic capacity of two multichannel cordless telephone systems using different dynamic channel allocation schemes in their call set-up and termination procedures. One uses a dedicated control channel and the other uses any free channel for signalling purposes.
