Is 'traditional medicine' mumbo-jumbo, as I was given to understand as a doctor's son in then British-run Uganda? Any link the witch-doctors had with modern times was the constant pinching of syringes from Mulago Hospital. They plunged them into their customers with unsterilised needles, I remember overhearing. Victims often ended up being treated in Mulago, occassionally with cattle urine in t...

Tiring of the touts and tourists in Kathmandu, I decided to travel to Pokhara to see the sun rise over Annapurna. In order to experience the rural way of life of the Nepalese, I scorned the comfortable tourist-bus in favour of the service-bus used by the peasants. At ?1.30 for a journey of 130 miles it seemed a bargain? but subsequent experience proved otherwise. Kathmandu bus-station is a mech...

Dynamic Location Control for Mobile Nodes

Mobile IP is the proposed standard of IP based protocol for mobile internetworking. Mobile nodes register with their home agents for location updates as they roam across IP subnets. IP datagrams for mobile nodes are routed rst to their home agents before being tunneled to mobile nodes through their current foreign agents. This paper investigates dynamic location control for mobile nodes and int...

Integration of IP Mobility in OPNET: Modeling and simulation

Using the base MIP protocol, two routing inefficiencies can be observed. The first is what’s called triangular routing: all traffic for the mobile node has to go through the home agent, increasing the routing path from the corresponding node to the mobile node. A possible solution is to let the correspondent nodes tunnel traffic directly to the care-of address: when the home agent first interce...
