Quick Sam | Re: MPC Question Paper Anna University As you want I am here providing you here sample question paper of Mobile and Pervasive Computing subject of a course of Anna University. Sample paper : 1. What are the main problems of signal propagation? Ans: Power additionally influenced by fading (frequency dependent) shadowing Reflection at large obstacles Refraction depending on the density of a medium oscattering at small obstacles Diffraction at edges 2. Give the use of SDMA. Ans: Space Division Multiple Access (SDMA) is used for allocating separated spaces to users in wireless networks. The basis for the SDMA algorithm is formed by cells and sectorized antennas which constitute the infrastructure implementing space division multiplexing (SDM) 3. Define GPRS. Ans: The General Packet Radio Service provides packet mode transfer for applications that exhibit traffic patterns such as frequent transmission of small volumes. 4. What do you mean by DAMA? Ans: Demand Assigned Multiple Access Channel efficiency only 18% for Aloha, 36% for Slotted Aloha (assuming Poisson distribution for packet arrival and packet length). Reservation can increase efficiency to 80% 5. What are the various versions of a physical layer defined in IEEE 802.11 standards?
