Which among the following is applied to resolve contention between use

1.	Which among the following is applied to resolve contention between users in non-cooperative intra-network spectrum sharing?(a) Random access techniques(b) Multiple access techniques(c) Spread spectrum techniques(d) Multiplexing techniquesThis question was posed to me by my college professor while I was bunking the class.I would like to ask this question from Next Generation Wireless Network topic in chapter Next Generation Wireless Network of Cognitive Radio
Answer» The correct choice is (a) Random access TECHNIQUES Explanation: Non-cooperative intra-network spectrum sharing is a rule based spectrum access approach. When more than ONE CLOSELY located nodes access the same channel, random access techniques are used to resolve contention. The RULES help to reduce COMMUNICATION overhead.
