一种基于CDMA的多信道自组网MAC协议(英文)
ACDMA-BasedMulti-ChannelSelf-OrganizingNetworkMACProtocol
Withtherapidgrowthofwirelesscommunicationtechnology,thedemandforreliableandefficientwirelessnetworkshasincreasedexponentially.Multi-channelnetworkshaveemergedasapromisingsolutiontoaddresstheincreasingdemandforwirelessbandwidth.However,theconventionalwirelessnetworksareinefficientinutilizingavailableresourcestomeetuserdemands.Therefore,anewMACprotocolisneededtooptimizetheuseofwirelessresourcesinamulti-channelself-organizingnetwork.
Inthispaper,weproposeaCDMA-basedmulti-channelself-organizingnetworkMACprotocol.ThisMACprotocolutilizesseveralkeycomponents,includingchannelassignment,MultipleAccessControl(MAC)scheme,andpowercontrol.Theprotocolisalsodesignedtoworkinaself-organizingnetworkenvironment,allowingthenetworktoadapttodynamicchangesintopology,trafficload,anduserdemands.
