Due to the dynamic environment, such as the roaming of mobile subscribers, maintaining a high radio frequency (RF) availability is one of the most challenging aspects in wireless network management. To date, in wireless network management, a call is dropped when the channel it uses goes down. In order to increase system end\u2010to\u2010end availability, an RF channel recovery scheme is proposed in this paper. When an RF channcl Pds, the channcl is replaced by another working channel and the call continues. The methods to replace failed RF channels of ongoing calls and to handle channel failures of handoR and new calls are investigatcd. Markov reward models are developed to compare system availability and performance. Automated generation and solution of Markov reward modcls is facilitatcd by a version of stochastic Petri nets that we call stochastic reward nets. The results show that the rccovcry schcme reduces the dropped calls and the blocked calls significantly under both light and normal trarffics.<\/jats:p>","DOI":"10.1002\/ett.4460110408","type":"journal-article","created":{"date-parts":[[2008,9,12]],"date-time":"2008-09-12T14:59:22Z","timestamp":1221231562000},"page":"395-406","source":"Crossref","is-referenced-by-count":11,"title":["Channel Allocation with Recovery Strategy in Wireless Networks"],"prefix":"10.1002","volume":"11","author":[{"given":"Yue","family":"Ma","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James J.","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kishor S.","family":"Trivedx","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,9,12]]},"reference":[{"key":"e_1_2_1_2_2","volume-title":"Wireless Access and the Local Telephone Network","author":"Calhoun G.","year":"1992"},{"key":"e_1_2_1_3_2","volume-title":"Radio System Design for Telecommunications","author":"Freeman R.
