Variety of Services Supported• type 1 (uni-directional single message transmission)
– advertise or discover with transmitting data
• type 2 (bidirectional single message transmission)– discover request and response with transmitting data
• type 3 (delay tolerant message transmission)– establish a contention access link after discovery
• type 4 (delay tolerant message transmission for open peer group)– establish a contention access link – allow a join after completing initial discovery
• type 5 (reliable message transmission)– establish a guaranteed access link after discovery
• more service types can be listedSlide 3

Frame Steams Generated from Services
• specification of frame streams– arrival pattern of frames
• inter arrival time• duration of discovery, peering, communication
– dependent on a service characteristics
– volume of frames • dependent on a service characteristics
• What MAC primitives can support the variety of frame streams ?– superframe structure– else ?

IEEE 802.15.4 Superframe
• Beacon Interval– one superframe between BI– Beacon Order
• inter arrival duration of superframe– Superframe Order
• length of superframe– inactive period
• 2BO – 2SO
• Multi-superframe– allocate superframes on whole beacon interval– Multi-superframe Order
• inter arrival duration of beacon appearance– can change CAP into CFP

PAC Superframe Operations• operations to hop on a superframe
– find synchronization period, transmit sync signal– listen for discovery period or send discovery, find a peer– if peering needed, exchange peering control frames– if resource slot in CFP needed, negotiate within scheduling period
• listen a superframe– listen for synchronization period– listen for discovery period, if still chances are open to find peers– listen for peering period, if still peering goes on– listen for CAP– listen for scheduling period of CFP– listen for slots in CFP, if find a peer who wants to communicate
• duration of wakening up

Extension of PAC Superframe (I)• introduce inactive period and multi-superframe
– specify operation in inactive superframe– combine active and inactive superframes
• PAC superframe– generic superframe
– superframe use CAP only
– superframe in inactive

Extension of PAC Superframe (II)• how to combine active superframes and/or inactive
superframes– PAC multi-superframe
• number of active superframe• number of inactive superframe
– cyclic superframe• combined active superframes and inactive superframes
