In this paper, we present a secure one-way mobile payment system that executes only two modular multiplications, one modular inverse and two hashings by the customer using two public key pairs and keyed hash function. Thus the customer(i.e. mobile device) conserves low computation load without any expensive modular exponentiation required for RSA or(More)
In mesh networks, various types of routing matrix are applicable. This document proposes a routing methodology, which makes use of the ETR (Expected Transmission Rate). The ETR is based on a load balancing metric contingent on the linked bandwidth of each integrated node. This routing methodology can be applied when selecting a relay node based on the(More)
