Mobile Computing Projects

Concepts involved in mobile computing

• Designing authentication protocol.
• Effectively handling security issues.
• Support high speed access and increase capacity.
• To achieve end to end Qos of network.
• Support for data and functionality migration.

Applications of mobile computing:

• Wearable computing.
• Intelligent house.
• Taxi/police/fire squad fleet.
• Smart mobile phone.
• Military/security.
• Vehicles.
• Nomadic user.
• Disaster relief.
• Service worker.
• Games.
• Invisible computing.

Sample code for mobile computing in ns2 Simulation:

This is the code of under water dbr routing protocol routing table information. This is applied in the field of under water sensor network.
dbr_rt_entry::dbr_rt_entry()
{
int i;
rt_req_timeout = 0.0;
rt_req_cnt = 0;
rt_dst = 0;
rt_seqno = 0;
rt_hops = rt_last_hop_count = INFINITY2;
rt_nexthop = 0;
LIST_INIT(&rt_pclist);
rt_expire = 0.0;
rt_flags = RTF_DOWN;
/*
rt_errors = 0;
rt_error_time = 0.0;
*/
for (i=0; i < MAX_HISTORY; i++) {
rt_disc_latency[i] = 0.0;
}
hist_indx = 0;
rt_req_last_ttl = 0;
LIST_INIT(&rt_nblist);
