1.rar - We present a genetic algorithm which is distributed in two
novel ways: along genotype and temporal axes. Our algo-
rithm fi rst distributes, for every member of the population,
a subset of the genotype to each network node, rather than
a subset of the population to each. This genotype distri-
bution is shown to off er a signifi cant gain in running time.
Then, for effi cient use of the computational resources in the
network, our algorithm divides the candidate solutions into
pipelined sets and thus the distribution is in the temporal
domain, rather that in the spatial domain. This temporal
distribution may lead to temporal inconsistency in selection
and replacement, however our experiments yield better effi -
ciency in terms of the time to convergence without incurring
signifi cant penalties.,2010-08-31 11:59:56,下载20次

ttye.rar - To improve network spect ral efficiency , a network coding2aware met rics for wireless routing
expected coding2aware t ransmission count ( ECTX) is proposed. In general , there are two steps in cod2
ing2aware routing communication : one is finding coding opportunity and network2coded node in the
routing discovery phase , the other is determining the optimum path f rom the coding2available paths
and the coding2unavailable ones. The expected coding2aware t ransmission count fairly quantifies the
network coding gain while considering the wireless t ransmission conditions. We implement the ECTX
routing in wireless mesh system in C + + and conduct extensive evaluation. Simulation result s illust rate
that , compared with the ones which oblivious of coding gains using , the t ransmission efficiency can be
sharply increased in the whole network and achieves 5 ～20 throughput gains.,2010-06-12 19:56:42,下载4次

such systems are very vulnerable to contamination at tack , and the signatures for t raditional network are no longer suitable for
network coding. Network coding allows the forwarding and receiving nodes to verify the coded messages against the contamina2
tion at tacks. In this paper , we proposed a network coding signature scheme based on homomorphism public cryptography which
uses the one time secrete key and it changes along with the change of the messages , so that it is infeasible for adversary to get
the secrete key and forge the signature to contaminate the message,2010-06-12 19:49:39,下载4次
