Note : questions may repeat from mid term examination so be prepared list various design issues for wireless network Wireless networks can have a number of design issues, including: Interference: Interference from other wireless networks and electronic devices can negatively impact the performance of a wireless network. Range: The range of a wireless network is limited and can be impacted by obstacles such as walls and furniture. Bandwidth: Wireless networks must share bandwidth with other devices on the same frequency, which can lead to congestion and slow speeds. Security: Wireless networks are inherently less secure than wired networks, as wireless signals can be intercepted more easily. Power Management: Wireless devices rely on batteries and need to be designed with power management in mind to conserve energy and extend battery life. Roaming: Roaming from one access point to another can cause connection issues and interruptions in network coverage. Handoff: The process...
GGSIPU | B.TECH | 8th Semester | Mobile Computing | Unit 3 & 4 Unit 3 a) Discuss Mobile IP. What are modifications in TCP for Mobile environment? Mobile IP is a protocol that allows mobile devices to maintain connectivity while moving across different networks. It enables seamless mobility by assigning a unique IP address to the mobile device, which remains constant regardless of its location within the network. Mobile IP consists of three main entities: the mobile node (MN), the home agent (HA), and the foreign agent (FA). The MN is the mobile device itself, while the HA and FA are network entities responsible for managing the movement of the MN. The HA acts as the anchor point for the MN and is responsible for maintaining its permanent IP address, known as the home address. Whenever the MN moves to a foreign network, it registers its temporary care-of address with the FA in that network. The FA then forwards packets destined for the MN to its current care-of address. Now,...
