SIGMOBILE

SIGMOBILE is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SIGMOBILE rather than just read about it. In short: SIGMOBILE is the Association for Computing Machinery's Special Interest Group on Mobility of Systems, Users, Data and Computing, which specializes in the field of mobile computing and wireless networks and wearable computing. Conceived in early 1995, ACM SIGMOBILE started out as an organization that fostered research in the "field of mobility and tetherless ubiquitous connectivity".

Key takeaways

SIGMOBILE belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SIGMOBILE to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SIGMOBILE from memory before moving on to harder problems.

Reference excerpt

SIGMOBILE is the Association for Computing Machinery's Special Interest Group on Mobility of Systems, Users, Data and Computing, which specializes in the field of mobile computing and wireless networks and wearable computing. Conceived in early 1995, ACM SIGMOBILE started out as an organization that fostered research in the "field of mobility and tetherless ubiquitous connectivity". It was founded as a provisional SIG on June 13, 1996, gaining permanent status on October 12, 2000. On February 8, 2005, the SIGMOBILE Chapter Program was launched. The NTU Singapore chapter became the first Student Chapter, and the Sydney, Australia Chapter became the first Professional Chapter. SIGMOBILE sponsors four annual international conferences: MobiCom, the International Conference on Mobile Computing and Networking; MobiHoc, the International Symposium on Mobile Ad Hoc Networking and Computing; MobiSys, the International Conference on Mobile Systems, Applications, and Services; and SenSys, the ACM Conference on Embedded Networked Sensor Systems. SIGMOBILE publishes a quarterly journal, Mobile Computing and Communications Review (MC2R), as well as the annual Proceedings of the conferences and many workshops sponsored by SIGMOBILE such as HotMobile, the International Workshop on Mobile Computing Systems and Applications.

Worked examples

Example 1 — a first encounter with SIGMOBILE

Start with the simplest possible case. Write down what SIGMOBILE claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SIGMOBILE before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SIGMOBILE ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SIGMOBILE

In research: SIGMOBILE appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses SIGMOBILE in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: SIGMOBILE is common in secondary-school and first-year university syllabi. It links to neighbouring topics Association for Computing Machinery Special Interest Groups, Computing stubs, so understanding it makes those chapters shorter.
In everyday life: Look for SIGMOBILE outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is SIGMOBILE in simple terms?

Why does SIGMOBILE matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study SIGMOBILE?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
