By dynamic priority assignment the authors propose to implement cognitive radio in the unlicensed band. In time critical events, the data which is most important, has to be given the time slots. Wireless Sensor nodes in the authors\u2019 case are considered to be mobile, and hence make it difficult to prioritize one over another. A node may be out of the reach of the cluster head or base station by the time it is allotted a time slot and hence mobility is a constraint. With the data changing dynamically and factors such as energy and mobility, which are major constraints, assigning priority to the nodes becomes difficult. In this paper, the authors have discussed about how Wireless Sensor Networks are able to allocate priorities to nodes in the unlicensed band with multiple parameters being posed. They have done simulations on NS-2 and have shown the implementation results.<\/p>","DOI":"10.4018\/ijwnbt.2012040104","type":"journal-article","created":{"date-parts":[[2013,9,13]],"date-time":"2013-09-13T20:01:31Z","timestamp":1379102491000},"page":"47-54","source":"Crossref","is-referenced-by-count":0,"title":["Heterogeneous Dynamic Priority Scheduling in Time Critical Applications"],"prefix":"10.4018","volume":"2","author":[{"given":"Arvind","family":"Viswanathan","sequence":"first","affiliation":[{"name":"Shanmugha Arts, Science, Technology & Research Academy University, Thanjavur, Tamilnadu, India"}]},{"given":"Garimella Rama","family":"Murthy","sequence":"additional","affiliation":[{"name":"International Institute of Information Technology, Hyderabad, Andhra Pradesh, India"}]},{"given":"Naveen","family":"Chilamkurti","sequence":"additional","affiliation":[{"name":"La Trobe University, Bundoora, Melbourne VIC, Australia"}]}],"member":"2432","reference":[{"key":"ijwnbt.2012040104-0","article-title":"NeXt generation\/dynamic spectrum access\/cognitive radio wireless networks","author":"I.
