Mobile Middleware for Body Sensor Network : A Grid Approach
Rossi Kamal,Choong Seon Hong 한국정보과학회 2010 한국정보과학회 학술발표논문집 Vol.37 No.2B
Wireless Existing mobile middleware for BSN (Body Sensor Network) has software agents both on sensor and gateway nodes. Software agents on BSN nodes depend entirely on that of gateway to connect to server. There must be a way by which sensor nodes themselves can communicate in BSN and connect to server. This paper solves the problem with a grid approach for mobile middleware on BSN. Sensor nodes (equipped with this middleware) with grid computing can operate entire BSN and perform QoS and security operations..
Event-Based Middleware for Healthcare Applications
Rossi Kamal,Tran Hoang Nguyen,홍충선 한국통신학회 2012 Journal of communications and networks Vol.14 No.3
In existing middleware for body sensor networks, energy limitations, hardware heterogeneity, increases in node temperature,and the absence of software reusability are major problems. In this paper, we propose an event-based grid middleware component that solves these problems using distributed resources in in vivo sensor nodes. In our multi-hop communication, we use a lightweight rendezvous routing algorithm in a publish/subscribe system of event-based communication. To facilitate software reuse and application development, a modified open services gateway initiative has been implemented in our middleware architecture. We evaluated our grid middleware in a cancer treatment scenario with combined hyperthermia, chemotherapy, and radiotherapy procedures,using in vivo sensors.

Towards Evolutionary Approach for Thermal Aware In Vivo Sensor Networks
Rossi Kamal,Choong Seon Hong 한국정보과학회 2012 한국정보과학회 학술발표논문집 Vol.39 No.1D
Wireless sensor networks have taken immense interest in healthcare systems in recent years. One example of it is in an in vivo sensor that is deployed in critical and sensitive healthcare applications like artificial retina, cardiac pacemaker, drug delivery, blood pressure, internal heat calculation, glucosemonitoring etc. In vivo sensor nodes exhibit temperature that may be very dangerous for human tissues. However, existing in vivo thermal aware routing approaches suffer from hotspot creation, delay, and computational complexity. These limitations motivate us toward an in vivo virtual backbone ,a small subset of nodes, connected to all other nodes and involved in routing of all nodes, -based solution. A virtual backbone is lightweight and its fault-tolerant version allows in vivo sensor nodes to disconnect hotspot paths and to use alternative paths. We have formulated the problem as m-connected k-dominating set problem with minimum temperature cost in in vivo sensor network. This is a combinatorial optimization problem and we have been motivated to use evolutionary approach to solve the problem.
