Abstract
A two-phase energy efficient collaborative spectrum sensing (CSS) strategy, namely EE-CSS, was proposed in [1], and expressions were derived for the steady-state (long term) average trust values and number of transmitted reports for honest as well as malicious secondary users. In this paper, we study the transient behavior of these quantities. A closed form expression is derived for the transient behavior of the average trust values. An event-based method for computing the average number of transmitted reports is described and its computational complexity is discussed. An approximate method as well as upper and lower bounds are proposed for the average number of transmitted reports. The results are verified using computer simulations.
