if As j (t) = h, if As j (t) = h. using jdk toencode qr code in web,windows application EAN 128 (7.41). At some interv al mT , we can approximate Us j (h, x s j ) by . Us j (h, x s j ) =. 0 t mT h Us j QR Code for Java (As j (t), A s j (t))1s j (t) 0 t mT h 1s j (t). (7.42). where Us j (As QR Code 2d barcode for Java j (t), A s j (t)) is the payoff value for s j determined by (7.10) (7.12).

The numerator on the right-hand side of (7.42) denotes the cumulative payoff of user s j when s j chooses pure strategy h from time 0 to mT , while the denominator denotes the cumulative total of the number of times strategy h has been adopted by user s j during this time period. Hence, (7.

42) can be used to approxi mate Us j (h, x s j ), and the approximation becomes more precise as m . Sim ilarly, Us j (x) can be approximated by the average payoff of user s j from time 0 to mT , . 1 Us j (x) = m Us j (As j (t), A s j (t)).

. 0 t mT (7.43). Then, the deriva tive x h,s j (mT ) can be approximated by substituting the estimations (7.42) and (7.43) into (7.

18). Therefore, the probability of user s j taking action h can be adjusted to x h,s j ((m + 1)T ) = x h,s j (mT ) + s j Us j (h, x s j ) Us j (x) x h,s j (mT ), (7.44).

with s j being tomcat qrcode the step size of adjustment chosen by s j . Equation (7.44) can be viewed as a discrete-time replicator-dynamic system.

It has been shown in [187] that, if a steady state is hyperbolic and asymptotically stable under continuous-time dynamics, then it is asymptotically stable for suf ciently small time periods in corresponding discrete-time dynamics. Since the ESS is the asymptotically stable point in the continuous-time replicator dynamics and also hyperbolic [124], if a player knows precise information about x h,s j , adapting strategies according to (7.44) can give convergence to an ESS.

With the learning algorithm, users will try different strategies in every time slot, accumulate information about the average payoff values on the basis of (7.42) and (7.43), calculate the probability change of some strategy using (7.

18), and adapt their actions to an equilibrium. The procedures of the proposed learning algorithm are summarized in Table 7.2.

By summarizing the above learning algorithm and analysis in this section, we can arrive at the following cooperation strategy in decentralized cooperative spectrum sensing.. Evolutionary cooperative spectrum sensing games Table 7.2. A lea jsp qr codes rning algorithm for ESS 1.

Initialization: for s j , choose a proper step size s j for s j , h A, let x(h, s j ) 1/. A. 2. During a per qr bidimensional barcode for Java iod of m slots, in each slot, each user s j chooses an action h with probability x(h, s j ) receives a payoff determined by (7.10) (7.

12) records the indicator function value by (7.41) 3. Each user s j approximates Us j (h, x s j ) and Us j (x) by (7.

42) and (7.43), respectively 4. Each user s j updates the probability of each action by (7.

44) 5. Go to Step 2 until convergence to a stable equilibrium occurs. Denote the proba bility of contributing to sensing for user si S by xc,si , then the following strategy will be used by si . If starting with a high xc,si , si will rely more on the others and reduce xc,si until further reduction of xc,si decreases his throughput or xc,si approaches 0. If starting with a low xc,si , si will gradually increase xc,si until any further increase of xc,si decreases his throughput or xc,si approaches 1.

si shall reduce xc,si by taking advantage of those users with better detection performance or higher data rates. si shall increase xc,si if cooperation with more users can bring a better detection performance than that in the case of single-user sensing without cooperation. In the next section, we will demonstrate the convergence to the ESS of the distributedlearning algorithm through simulations.
