In this study, an analytical uplink modeling for CWSN is introduced. Detailed mathematical analysis of the outage probability, throughput, affected area and delay sensitive area spectral efficiency (DASE) for fixed network is defined and also the outage probability and affected area is derived in random network considering of the probabilities of unoccupied by the channel selection and successful transmission for imperfect detection. The numerical results for fixed network are analyzed depending on theoretical expression which shows that optimal transmission power is efficient to find the maximum value of DASE and for this reason the RF pollution is low.64 pagesenBrac University theses are protected by copyright.
